Just one suggestion, just because other people are already started doing what you thought was a good idea does't mean you give up on it. if this is the case then none of the following companies existed : Microsoft, Google, Apple, Yahoo, Cisco etc etc.

Just pick what you are mostly interested and start finding a niche which is useful to the users. The most important thing is to develop some thing users want. If you can figure out that then your already won your 50% battle.

I think you might already know this but it is worth while repeating. Idea is not important, execution is the most important thing
