I read people using web2.0's all the time (and doing it my self as well) .. but I'm curious to how exactly you are using these services. Are you just registering for a profile link? Are you creating blogs/domains with just 1 post/page? Are you creating side wide links to your moneysite or just in the post(s)? Do you link to other relevant sites (with nofollow), even competitors? Are you perhaps even monetizing these sites with alternative methods/services? .. like to here everyones approach to this!
