Gravatar Icons...

Just as "uservoice" and so many other websites do, I think it'd be cool if you guys implemented "gravatar" icons into your app so people can create a centralized icon for usage on multiple sites, and then you guys could use this icon for chats with visitor or other agents to make the experience more personal, without having to re-invent the idea of uploading an icon to yet another website.
