Use .edu, then .net. Don't use .info. Google sees .info as trash sites. There is a reason the .info sites are only 1.99 on GoDaddy. And I don't think GoDaddy even shows .edu sites. You will have to go to NameCheap.com for those site listings. A .edu site will give your traffic them impression your site is for educational purposes, even if you are planning to market a product or service. WC
http://en.wikipedia.org/wiki/.edu You can't register edu unless your an accredited postsecondary institution such as a college. For OP...I like .net but you seem to need .in for your audience.
Do you have any proof to back that up? Seems that if Google was penalizing .info's because there are so may spam sites on that extension, they would penalize their own blogger...there are far more MFA's and crappy blogs that are just an excuse to throw up a adsense, or banner farms than anywhere else on the web. Bad advice. .edu is not available to everyone, and that is why.
My _normal_ response (if you were appealing to an English-speaking, worldwide audience) would be: You're not going to like my answer, but find a different domain name. It's a time-proven fact that people automatically jump to the ".com" version of any domain name in their heads. I'm not saying it's *impossible* to have a successful website with a .anythingelse if the .com is taken, but you're going to suffer a lot of lost traffic and it will be all-in-all harder for your site to be big. But in your case, if you're *targeting* an Indian audience, what appeals to an English-speaking worldwide audience does not matter. Go for the .in.
