Recessions are good times to for social "fun" sites too - HotOrNot, Blogger, LiveJournal, PlentyOfFish, Flickr, and Friendster were all started either right before or during the 01-02 recession, and Disney got its start in the middle of the Great Depression. You just gotta keep your cash outlays less than expenses, find a revenue stream other than advertising, and build something attractive enough that at least some people are willing to pay for it.
