This post is from one of several previous incarnations of this site and probably doesn’t quite fit the current format. In a former life this was a group blog and a tumblelog before it became a static jekyll site. If anything looks broken or is worded oddly that could be why. Pardon the dust.
What webapps need primarily is better desktop integration in the local storage and drag-and-drop sense. Not in the one app per window and a cute little icon in a dock sense.
