Ok all i need is a resource that can enlighten me what web 2 sites eg Wordpress, Blogspot, Tumblr are dofollow. Having scoured google the best I can find regarding whether a web 2 site is dofollow is look at the source code.
That would be V tedious and time consumming.
So is there a shortcut? A directory of sorts that lists do follow sites, is it out there in some hidden recess of the expanding world of cyberspace…
Thanks in advance 
You don’t need to look at the source code, you can just install a decent firefox SEO plugin that will how you what links are nofollowed and which are not when you load a page (I have one installed at home, SEOQuake I think?).
I don’t really use it for that purpose, I use it to gauge competitiveness in SERPs by seeing backlink counts and the such right on the search pages.
I’m sure there also lists of dofollow sites out there, did you try Googling some search terms? A quick trip to Google shows many sites that have these lists for me.
The SEO-moz tool bar has a handy “Show Nofollows” button that highlights what links on the page are/aren’t followed.
