After reading the discussion (all 14 comments that exist right now), it seems that people have given you plenty to think about. It looks like you wanted to make a web app that was simple, interesting, and attainable. For that, I give you an A+. Using the Twitter API is good practice because its extremely popular. That said - the added value of something like this is probably minuscule in comparison to the effort it took to make it - especially nice and polished like it is. In any case, I bet you have a list of things you learned, plus a working demo on the web of your capabilities. Kudos!
