suggestion's for domain name ?(Autoblog)

Hi guys,

I wanna register a main domain name for auto blog's,
so lets say the main name is xxxx.com and i will just create
TechNews.xxxx.com, Fitness.xxxx.com.

any idea's what may be a good main domain for this? or maybe give me some example. or if you got some experience with auto blogs should each blog has his own domain? :O but it's lil bit expensive for 100+ blog's

Thanks alot.

Start with a few domains. Although if you don't really want to invest in domains, you can register at co.cc. Its free for one year, after that u have to pay 3$ per domain to continue. Although I would still recommend going with any good supported domains like .com or .org. Google gives them more priority.
