I fell in love with darcs (switched from git) and wanted a place to put my stuff, since github would no longer be of much use to me. So I made it. Right now I just add things as I need them, or think they'd be a good idea (like "ssh username@darcsden.com init reponame"). Been meaning to get around to built-in issue tracking, but I'm busy working on other projects.
