We all know that Web 2.0 sites are a great way to get backlinks however right now I only know 5 dofollow ones so please link me to some that you are using
Here's a few: Wordpress Blogger Weebly Hubpages Squidoo Although those are probably the 5 that you already knew.
Hubpages is do-follow after you get your Hub score to at least 75. Another one I forgot to mention is Scribd. Here's a link I found today of a big list of do-follow social networking sites, check it out: http://dofollow.info/dofollow-social-media-networks/
Most I know off but thanks anyway guys btw didn't know about hub pages and the do-follow thing, so thanks for letting me know.
