ASK HN: Feedback on my weekend project http://lb.anishoo.com

Hi, Long time reader and first time poster. I recently changed jobs and moved to web development engineer role working on the LAMP stack. As part of ramping up I had started a hobby application in LAMP that I thought had use at that time. Its been 6 months since then and have finally managed to get it working enough to open for feedback. My intent is to provide services for mobile/dektop platforms and started off with a Leaderboard service that I needed for my WP7 games at that point. I know there is enough similar services out there but I do have some ideas on other services to add to this eventual portfolio that will be different. Let me know what you guys think about this.
