Hi,social net working sites are catching up fast in india too like in america. as indians generally adopt wait and see approach these sites will grow slow and steadily.The massive spending on ads promotion may not healp much in india as i feel sites with novel ideas presenting in attractive user required ways will have great future.It appears all thesse young guys have great opportunities.It appears three sites have good financial backing and some site like "Indyarocks.com" appears to have taken up some social cause linking up rural youth,through NGOs to urban corporate sector to facilitate employment.It is a noble cause apart from pursuing their business goal.It would be good others also take up such noble causes to help rural india also enjoy some benifits of reforms and advanced technologies. I wish good luck to all this young entreprenures and your presentation is excellent.
