The way I see it, there are two big opportunities for startups in hard times.<p>Firstly, some old businesses will be shutting their doors, and every time a business closes down it leaves behind a bunch of unserved customers, who presumably could be served at a profit by a more efficient business.<p>Secondly, people will be more likely than they are in boom times to break out of their existing habits and move to a lower-cost competitor. If you can find a way of providing people with things they <i>need</i> at a lower cost than the existing players, you can grow really fast.<p>Startups which exist to provide people with new and innovative ways to poke each other, on the other hand, might not do so well.<p>Oh, and one additional idea to throw out there while I think of it: a site aimed at highly-skilled but newly unemployed workers, with a combination of job-finding tools and commiseration.
