Whats your favourite web 2.0 creation site and why?

Hello warriors

I am a bit sick of paying up 10 bucks for every new domain for each new niche or whatever that takes my fancy! So I have decided to use web 2.0 to create my affiliate product FPA/articles.

Whats your favourite, taking into consideration seo benefits,possibility of getting banned, ammount of ads they display etc.?

So far I have decided squidoo can drop lenses at the drop of a hat (see many pages that have massive backlinks but the lens has been removed (DOH!) . I have also decided against hub pages as they really ruin your page with huge banners with niche displayed ads to take your traffic (fair enough for them to make big money good on them).

So that leaves me with weebly who look really cool but the interface makes me want to rip my hair out its so slow, and then theres the google sites and knol that look cool, less likely to be removed, good seo of course, and blogspot that arent likely to be removed etc. Wordpress sucks as they remove even good articles if they have one too many links etc.

So whats your favourite 2.0 creation site and why?

thanks for reading
