My issue with web2.0 is this: Lots of good products by people that don't know how to market them. Viral marketing is a misnomer. You need to SEED viral marketing. You usually need to BUY your first 50,000 users. Once in a while there is an exception but you need to market.

Myspace for example was seeded. They had 300 employees and they have a contest where the employee who got the most friends would win $1000. The average person got 30 friends = 10,000 users.

Then they did email blasts to millions of opt-in records, probably another 40,000 users

In total they seeded it with at least 50,000 users in less than a week. Then it took off.

So Mr. Web2 - what's your seed marketing plan?
