Hefty competition on all fronts, I'd probably try looking for another not so congested market if I was you, unless you have some marvelous mechanism big players won't be able to implement.

But if you must I'd possibly look at the social networking reporting for a couple of reasons.

- The market is hot and you might be able to get funding or flick it easy

- It looks like all the other projects are going to need an decent advertising base, and (as long as you build carefully) you'll be able to re-purpose parts of the social networking... so can look at as an investment
