The nice folks at 37Signals who already gave us Basecamp and Ta-da list, are teasing us with a preview of Backpack, their next web application. Looking at the name and others' comments, my bet is on a personal storage space, "a place to put stuff. Thoughts, files, ideas, lists, you know, stuff." as Justin French puts it. Those guys are set to give web applications their lettres de noblesse and I love that.
