Raphaël is small JavaScript library that should simplify your work with vector graphics on the web. In case you want to create your own specific chart or image crop-n-rotate widget, you can simply achieve it with this library.
Every time Dmitry has demo'd this at work I've been blown away. Basically it allows you to do cross-browser graphics manipulation in Javascript by providing an abstraction layer on top of whichever is available out of SVG or VML. MIT licensed, "supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+”
I like that the excerpt in the atom feed is the actual post content now. Do you feel like you're writing less?
Yours was the only site in the world where the atom feed contained text different than the article content.
"Oh, it's the fishbowl. I have read this blurb first, then go to Charles's site and start at the beginning again."
"Oh, it's XKCD. I have to read the comic, then hover over the image until to tooltip joke comes up."
There were different feeds for excerpts and full post content, it's just they were only listed a third of the way down the right-hand sidebar on the front page, and most people didn't find them.
