Are we heading to another bust ???

After news came out that YouTube has been bought by Google for $1.6 billion, it feels like being in the dot-com era. I think, history would remember this period as Web 2.0 era where user-generated contents score high than any other service. Last year myspace was sold for $560 and odd million and this year YouTube with 67 employees and just 14 months old with no profits have been sold for a staggering $1.6 billion. phew ! Are we heading for a Web 2.0 bust ???!!!
