Last week we kicked off a new blog series showcasing the amazing array of moments that occur #OnlyOnTwitter. We’re back again with highlights from this past week, which take Twitter to the deepest part of the ocean and a racecar driver’s seat in the sky.

James Cameron tweets from the seafloor
The director of Titanic took a very special trip—his was the second-ever dive to the bottom of the Mariana Trench in the Pacific Ocean. And that’s how he became the first person to send a Tweet from 35,755 feet below sea level.

You know those incredible moments that make Twitter so special — the ones you can’t help but tell somebody about? Over the last six years, Twitter has hosted many thousands of these, big and small: news events, conversations between celebrities, great creative hashtags, running jokes or debates.

We’ve started collecting these moments here over the last few months, and now we’re sharing them with you. Each week you’ll see instances from sports, television, news, music — and they all have one thing in common: they appear #OnlyOnTwitter.

Without further ado, our picks for the week:

The artists’ view of #SXSW Music
Bands and performers told their own stories at this year’s SXSW, tweeting their performances and those they enjoyed as fans. See Austin from the musicians’ perspective with Tweets from Kreayshwan, Richard Swift, Kimbra and more:

SXSW in 10 words : music, beards, beer, plaid, sweat, wristbands, perfectly, scuffed, boots, life.

An @-reply becomes a collaboration with Deadmau5
When electronic music producer/vocalist Chris James saw Deadmau5 was working on a new project, he tweeted to him with some possible vocals.

@deadmau5 did some unique shoegaze-ish vocals over "The Veldt" based on the story. Hope you enjoy soundcloud.com/chrisjamesoffi…

Walking Dead fan Q&A
As the second season of AMC’s popular zombie series drew to a close, executive producer Glen Mazzara fielded questions from fans.

Cross-posted on the TweetDeck blog.

Today, we’re releasing a new version of TweetDeck. This update introduces some great new features as well as a host of smaller improvements and bug fixes. Check out this video for a quick tour of the updates, and read on for more information.



List Management

You can now create, edit and delete lists directly in the app. There is even a dedicated Lists button on the toolbar, so you can quickly and easily dive in to manage your lists. Additionally, all user profiles have an “Add or Remove from lists” menu item, making it easy to manage list memberships for any Twitter user.

Activity & Interactions

We’ve added two columns to TweetDeck to make it possible to see additional activity on Twitter, including retweets, favorites and follows.

A new Interactions column, available under the Add Column button, is like an enhanced Mentions column. It shows not only all of your mentions, but also alerts when you have been followed, added to a list, retweeted or favorited.

Perhaps even more interesting is another new column type called Activity. This column shows a real-time feed of all the follow, favorite and add-to-list actions performed by the accounts that you follow. We think you’ll find this helps you discover lots of interesting accounts and content that you may not have previously seen.


Media Previews

TweetDeck now has inline media previews, so you can view images and videos faster and more easily. You will now see a small preview of images and videos under the related Tweet. If you’d rather not see in-line media, just turn this option off under Settings > General.

Additionally, you can view a large preview of images and videos in an in-app media gallery. Just click the preview image, or the URL in the Tweet, and the media will be displayed in a large gallery view.



Edit & RT

We listened to the feedback that the “Quote” retweet option was not as useful as the previously available “RT @username:” format. So, in this version, we’ve replaced “Quote” with “Edit & RT,” which lets you edit the Tweet before sending.

Six years may not be very long in human terms, but it’s been quite an enormous span for the thing we know and love as Twitter. When @jack first sketched out his notion in March 2006, no one could have predicted the trajectory of this new communication tool. Now it seems that there are as many ways to express yourself in 140 characters as there are people doing it. And at last check, there are more than 140 million active users (there’s that number again) — and today we see 340 million Tweets a day. That’s more than 1 billion every 3 days. However concisely, it turns out there’s plenty to say.

Without you, of course, there wouldn’t be a Twitter. We mark our sixth birthday with you in mind, and celebrate your myriad ways of engaging, enjoying, and emoting on our platform. As Jack noted when he posted his sketch of the service he envisioned, “I'm happy this idea has taken root; I hope it thrives.” Thanks to you, it is.

Today we are welcoming a very talented group from Posterous to Twitter. This team has built an innovative product that makes sharing across the web and mobile devices simple—a goal we share. Posterous engineers, product managers and others will join our teams working on several key initiatives that will make Twitter even better.

Posterous Spaces will remain up and running without disruption. We’ll give users ample notice if we make any changes to the service. For users who would like to back up their content or move to another service, we’ll share clear instructions for doing so in the coming weeks.

We’re always looking for talented people who have the passion and personality to join Twitter. Acquisitions have given us people and technology that have enabled us to more quickly build a better Twitter for you.

Here’s the Posterous post on today’s news.

With delegates from 10 states up for grabs, Super Tuesday has been a highly anticipated day on the path to the Republican nomination. This chart maps the conversation about each of the candidates over the course of the day. You can see the volume of Tweets increase sharply around the time the first results were reported, and additional lifts as each candidate addressed citizens and voters on TV.




The data surprise of the night? With an unexpectedly tight race in Ohio between @RickSantorum and @MittRomney, the conversation on Twitter about Santorum spiked far higher than any of the other candidates. In just the hour between 6pm and 7pm PT, there were nearly 40,000 Tweets referencing Rick Santorum. In fact, this is a new 2012 Election Twitter record. Our previous highest candidate spike belonged to Newt Gingrich, on the day he won the South Carolina Primary.

The data tells one part of the of the story, the Tweets tell another. Throughout the day, most of the top retweeted Super Tuesday Tweets were the funny ones. Note: The "Rmoney" photo is actually an image that was circulated in February, and has been confirmed to be a Photoshopped image, not a photograph.

You know that warm, tingly feeling you get when your foot falls asleep? That's how I feel about Mitt.

As the results began to come in, political reporters and political junkies alike were glued to their televisions—and sharing their insights on Twitter.

If Santo wins Ohio, the one thing he'll really want and need is another debate. The last one wasn't so good for him.

Finally, here’s our earlier blog post with charts that show the road to #SuperTuesday on Twitter in Tweets that mention candidates and candidate follower growth.

Today we’re launching Twitter in four new languages: Arabic, Farsi, Hebrew and Urdu.

We first added these four languages to the Twitter Translation Center on January 25. Thirteen thousand volunteers around the globe immediately got to work, translating and localizing Twitter.com into these languages in record time. Thanks to their contributions, Twitter is now available in right-to-left languages.

These 13,000 volunteers are a vibrant and diverse group. Among those who donated their time and translation skills to make right-to-left languages a reality on Twitter: a Saudi blogger, Egyptian college students, a journalist at the BBC, IT professionals in Iran and Pakistan, an Israeli schoolteacher, the co-founders of the grassroots #LetsTweetInArabic campaign, academics specializing in linguistics, and teenagers in Lebanon.

Some of these volunteers live in regions where Twitter is officially blocked. Their efforts speak volumes about the lengths people will go to make Twitter accessible and understandable for their communities.

Twitter is now available in 28 different languages around the world. Right-to-left languages posed a unique technical challenge, particularly with Tweets containing both right-to-left and left-to-right content. To solve this, our engineering team built a new set of special tools to ensure these Tweets, hashtags and numbers all look and behave correctly.

We want to thank all the volunteers for helping us making Twitter available to every person on the planet. If you want to help translate, join the community to discuss existing translations or suggest a new language for future translation, visit our Translation Center.

Since the beginning of the 2012 election season, many of you have turned to Twitter for breaking news about the latest GOP primary results, participating in the debates and first-person accounts of virtually everything happening on the campaign trail.

Your Tweets have also mirrored the rise and fall of various GOP prospects’ campaigns heading into Super Tuesday. Check out this graph charting the number of Tweets mentioning each of the Republican candidates throughout the campaign:



Update: Here is a chart of GOP candidate follower growth leading up to Super Tuesday.
