Free hosting/web 2.0 sites that allow you to use your own domain?

Does anybody have a list of free hosting providers or web 2.0 sites that allow you to add your own domain name for free? Aka I buy a domain thebestsiteingalaxy.com and then host the site on web 2.0 site or on the free hosting?

Thank you!

As per my experience each site does allow to use TLD.

for i.e

blogger.com
wordpress.com
tumblr.com

any many more..

Thanks for the suggestions. Anybody else?
