Since our last update, we’ve spotted a number of implementations of Gravatar around the web that we think are pretty neat. Here are a couple of them:

• MailChimp now supports Gravatar, loading them up as part of the member profile for any subscribers who belong to mailing lists you manage.
• Yoav emailed to let us know about Gravatar.NET, a package for .NET developers who want to make full use of the XML-RPC API to manage their images remotely. He is using his library on Ponderi.com, and has a tutorial about working with the XML-RPC API on his personal site.
• Rapportive is a very cool browser plugin that modifies your GMail screen so that you can see some information about the contacts you’re conversing with. It aggregates data from all over the place, including images and profile data from Gravatar.
• We’ve also heard a few whispers from folks who are playing with the new profile data and how that can be used in other applications as well — more on that in the future!

We really love seeing Gravatar pop up in new and different ways, so if you’ve heard of or seen any others, please let us know in the comments.
