MyProgs - find new software, keep your program list online: "This site allows you to keep a social list of the programs you use. After you sign up you can add programs to your unique list. You can view anyone else's programs and they can view yours. Extra user-defined data can be added to each program entry to organize and describe the program further such as program descriptions, a link to the program's homepage, and tags. You can use tags to categorize (and thus organize) programs so that you and others using this site will have an easier time finding new and interesting programs.
RSS feeds are available at almost every page which allows you to track new programs using your news aggregator."
This is really a great site!
I just added some of my programs. More to come ...
