I have like 15 sites that want a picture of me to show as an avatar. Which is great except if I ever decide to change things up. I don’t feel like like going to, or remember, all the sites I use at any given time so they are rarely in sync. I really wish people would jump on an avatar service like gravitar so that we don’t have to go all over the web tracking down old images every time we feel like changing. Plus, if you are using rails, and why aren’t you, then you can use this plugin to make it very easy to integrate.
