A couple of fun things I've been working on to learn some new programming skills, namely node.js and MongoDB.
1. News Bit -- Remember Share Your OPML? Me too!
2. Linkblog -- A super easy linkblog tool.
I plan to open source the linkblog code soon. It also uses a shorturl tool I'm working on -- shorturl is open source. I still need to hook the hit stats (collected by the shorturl tool) into the linkblog tool, but other than that the tools work well!
