For anyone using PayPerPost it's worth checking out their forums for info on hot topics.
Amongst the interesting tidbits are the following stats at the bottom of the forums index:
"Our users have posted a total of 7515 articles
We have 318 registered users"
Honestly, I'd thought they were bigger than that already ;)
I haven't read many of the forums yet, but the discussion about PPP promoting use a disclosure statement is very interesting. I was especially tickled that an advertising was pulling their business from PPP because of the "push" for disclosure! They said they "...only want honest reviews of my site", but at the same time were aghast that bloggers might reveal that it was a sponsored post... I think they need to reconsider the meaning of the word "honest"!
