:: autoblog :: free hosting + free domain + wordpress vs blogger

Hello all, I had been with a question in mind about autoblog.

Please tell me your thougths.

In one side I've an option of free hosting + free domain and create 100-300 blogs using wordpress.

In the other side 100-300 blogs in blogger.

So, what's the best option?

Is it blogspot better for seo results then free domain? or it's no matter that while we've traffic for the site.

Thanks a lot for all your help.

I have good experience with free hosting + free domain + wordpress

Where would you get 100-300 free domains to use with autoblogs?

Where do you guys get your free hosting to use with WP???
