After reading this and other forums I'm still wondering if it's just a useful tool or if Google's corporate agenda is coming in to play.

What are they trying to achieve by making comments etc. publically viewable ? I'm starting to think that they are going to monitor behaviour on this as well as CTR on the SERPS to ascertain you a score which is then incorporated in to the full Google Algo which gives you your final rank.

How much weight will they place on this ? Only time will tell.

(I suppose they had to do something new as most SEO's have given up with the Toolbar PageRank )
