I posted this in the Forums that Do Follow discussion, but it seems appropriate here
Courtney Tuttle has compiled a pretty good list of DoFollow blogs, some are no longer around but there are still a good few there http://courtneytuttle.com/blogs-that-follow/
Do follow is a plug in installed on self hosted Wordpress blogs which disables the "no follow" attribute.
Clear as mud, eh?
In plain English, the "standard" Wordpress blog software is set up so when you leave a comment on the blog, the search engines won't follow the link. That means that when you leave a comment on a blog without this plugin installed, that human visitors can follow the link but the search engines won't.
With this plug in installed, when you leave a comment on a do follow blog, the search engines will "count" that link as incoming link to your blog.
Not all search engines use the NoFollow anyway. Though it's always advisable to concentrate your efforts on link building using links without the nofollow - obviously.
This list certainly is very helpful. Would it be fine if I share the list I have been preparing too? I was preparing it for my own purpose in a spreadsheet, but I think it's good idea to share it here.
