A websites name is extremely important. Anyone that doesn't think that has never started a company. It needs to be simple, easy to say, easy to spell, and unique/meaningful.
Take eBay. This name actually has nothing to do with Auctions if you have ever read about where it came from, but it is perfect because it is unique, easy to say/spell, and brandable.
Don't underestimate a good name, it is an absolute necessity now with all the millions of websites out there.
