If you want to register an domain .in it's your choice. But this domain it's good for SEO Blogs , because indians are very interested in SEO and link building . I know that because a lot of indians are reading my dofollow list daily and they are commenting on this post . Most of my traffic it's from India, so if you want to make a SEO blog or related , it's very good a .in domain
I had quite a few .in domains that were parked and they made some good money for a while, but now Yahoo has banned them at the parking service I use, so I let most of them go. I still have a few that I want to develop like:
SellGold.in
SEOBusiness.in
My idea is to make use of subdirectories like this:
SEOBusiness.in/Minnesota
SEOBusiness.in/New York
SEOBusiness.in/Florida
SEOBusiness.in/California
etc.
I don't know if the ccTLD will help from a SEO standpoint, but I think the URLs will look good.
.in Domains with proper keywords and short domains like LLL.in's are really worth registering. just consider the population of India and the rising internet penetration day by day.
