I'm surprised no one has mentioned Gather.com. I think it is more useful than any of the other sites mentioned here, and it is dofollow.
i thanks to user for sharing the views and website.... for such resources i often go to a blog - niceblogger dot com That website is having good list.. you will like the list.. that had dofollow networking sites, dofollow high pr directories, dofollow forum list and many more... will take your little time in searching but you will get the result.
You don't need more search, high pr dofollow bookmarking sites are infront of you. See the mega list of 100 PR 3 Dofollow Social Bookmarking Sites and get the quality traffic to boost your site.
Gather.com is a social networking site and we can store our articles in this site. But for increase our backlinks we cannot rely only 1 site, we need a bunch of sites for move the traffic flow to our website.
Another site with dofollow : http://tutorials.iulzi.com/network/ , is a web community for web designers and web developers. It's a great place for designers that are searching for fresh articles, tutorials and resource for free.
Some nofollow sites provide good traffic but they can't provide backlinks to your website. Dofollow sites provide good traffic as well as they provide quality backlinks.
Thank you for taking the trouble to give us this list of links. I signed up with Mixx and started submitting links to my website.
