What's up with all the MyGenius buzz - are these paid reviews?

I am really, really surprised that Mike and Paul have blogged (and positively) about MyGenius. I joined this site a while back, signed up, put some stuff there to fill it up and dissappeared. That was that. I have not returned other than to delete my account.I am not fond of the site, don't tell me to give it another go, don't tell me what I'm missing because I know these things. Yet I still think the site is not for me.Why did Mike and subsequently Paul write about the website? Were these paid reviews? They felt as much but were not stated as such.My question is this: Why would I switch to a site that still has so much to do when I can visit many more that are already doing it?No, wait, that's not the end of this mini-rant. I know that MyGenius could open up another level of interaction, I know that there are different people on there, I know, I know. But read this sentence as I type it, I am not interested. Point. Blank. It is not appealing.
