I spent a few hours writing code for a personal micro blog. It will look vaguely like Twitter; but only one user, no threads, no responses/comments, and no images/videos. In otherwords, an actual micro blog, unlike Twitter.
I've written 99% of the code (130 lines so far). What remains is to correct the HTML generation code and to get the HTTP server working. I'm writing this in Common Lisp, which has made many things easy (e.g. multiple values). The database is very slick, and arguably only possible in Common Lisp (and maybe Scheme).
