i built exactly this last year, over a weekend ... it's at http://reduce.li http://reduce.li Though i dont maintain it anymore, there's basic visitor tracking by adding a + to the generated url, just like bit.ly. Very soon, online pharmacy bots started spamming me! In retrospect, looking at all the positive feedback here, I feel that where I went wrong was adding bloat like picture uploading/url shortening etc...
