Hello Mate,

I dont know, why you are making this simple this complicated and also making me complicated. Think it this way. Suppose you are making a web 2.0 on generic niche of basketball. And you are posing 2 article on it. Do internal and external links between all pages and posts of that web 2.0 first . Then manage 2 external links to 2 different basketball related posts (same site) or if you find opportunity to give link to 2 different posts like: 1 link for basketball shoe and 1 link for running show (2 different sites). You can do that as well.
No I dont want nofollow links for web 2.0 properties. Do you know is dofollow or nofollow? I just tried to create a demo blog and seem it is dofollow.
I have made an edit to the web 2.0 list after this issue. Removed the web 2.0s which are not working and assigned a new web 2.0 for those places and left a comment. Please check the yellow colored ones along with the comment. If jigsy is dofollow then I'll take it otherwise follow the associate comment.
