In my browser, google.in redirects to .co.in

My experience shows that it is often hard to say whether .ins or .co.ins are worth more. Probably we should distinguish two things. From the point of view of domain market related to quality/brandability of name (end user) IMO .ins are preferred (available sales data). From the point of view of type-in traffic domains market (people living in India - and this is popularity of the name/extension as well), it looks sometimes/often that they prefer .co.ins rather than .ins (I made such guesses registering both keyword.in and keyword.co.in). Sometimes .co.ins performed better. Therefore I guess many people defend .co.in - they see more type-in traffic to their .co.ins. But it is not the value of the name from the point of view of end user if he is not aware of traffic details etc.
So, while there are many factors affecting the whole picture (developed indian sites in gtld'ss or xxx.in's, foreigners which are probably not aware of .co.in, org.in etc.) and making it hard to clearly choose either .in or .co.in, generally speaking, IMO .in's are at least a bit preferred.

BTW, seriously, it is very interesting to see which extension big companies prefer more. I guess Google engineers or AOL engineers made big analysis to decide what extension their website will be on. And because we clearly see split decision (in whos favour?) it shows that probably there is no winner there yet.
