Paint.net is an absolute must-have. It is the tool I use to build all the graphics for my site although that may not be saying that much... :-) Congrats on shipping the final build guys. Great work.
In other news, did you see the Feeds Plus install for IE7? I use IE and Outlook for reading RSS because I like the concept of the central OPML and both tools use it. I'm a big fan of RSS Bandit and will switch back to it once it can use the Vista central OPML.
