Google has few of registered sites under their name. eg:- xxxxx.google.com xxxxx.info is what i have .. Well i have their subdomain's domain name.Those are infos and orgs but its weird that google didnt bother to buy them.
It could be a problem of trademark as most of the subdomains are promoting Google programs or function that could be patented. At least it's a info and the reg fee was low, in case Google decides to "redeem" it. And they have a habit of doing so.
yes, depends if it is generic or a trademark rabbits.google.com and rabbits.info is fine adwords.google.com and adwords.info is trouble
I happy with my domain though.I wont share until its one air.The good news is that google is starting up with that name quicking.U will come to know that soon.I am not foolin' any one.
