Note to Web 2.0 Companies: Early Adopters are not the Mass Market

"If you are a Web 2.0 company in today's Web you really need to ask yourselves, 'Are we solving a problem that everybody has or are we building a product for Robert Scoble?'"

Couldn't have said that better. There is a market for niche products online, to be sure. I think the problem is niche products pretending to be widely useful.
