It's also interesting that they do use the "authority" of the person posting as signal. This would, to some degree at least

I see a lot of risk there as in the current world,determining a person as clean is not that easy...unless a person is clean, we cannot say him to have real authority...

and as someone said about the paid tweets, we are going to see a huge jump in paid tweets and paid "likes", just like the paid links...

but it is good that these signals are not used widely (if it were true) and hope they don't make it so...

but it surely paves way for a new (or a much improved) revenue stream to online celebrities...
