Own domain on a web2.0

I came into possession of 30 domains that I whink all together will give me a bang - they are all 20+ DA and at least 2 quality high pr links. They are "Ok", not "Great". I would like to use them, but I dont want to pay a dollar or two a month for hosting for each of them.

So I would like to ask you if you know any web2.0 sites that will let me use my domain for free and allow d0f0llow linking?

Blogspot does....

Like lord1027 said, Blogspot does.
Others that I can think of is Wordpress.com and Tumblr.
