MySpace has now reached 47.3 million members and growing at 160,000 members per day!!
If this isn't wildfire, than what's more?

Even lot of indian youngsters (including some of my friends) are spending hours at social networking sites like Orkut, Hi5 and the others. And today I came to know about an interesting fact from one of my office colleagues. His friends are apparently using Orkut much more than their yahoo messengers! Surprised!

Beat these young indian software engineers who are now using sites like Orkut much more, as their companies have blocked access to yahoo messengers!!!
