i dont think, that will help to improve the power of the .co.in, you need power or visitors? if you need visitors then you have to use most friendly domain name extentsions. .in have that simplicity.
You consider it, in india, more than 50% peoples dont know how to browse the internet, or they didnt used internet before, in the other 50% half of them using computer for dating, chating and playing. If you can give what they want, user friendly then you can use .co.in or .in..
But i dont think some extentions get more power than other with a simple newspaper advertisement.
So my opinion is go beyond the news, go beyond user friendly good sites...and make sites for users or visitors dont create site for search engines or anything else.
