Oh I think the opposite is true. Most of what has been posted that is positive has been shown to be complete bullshit. If you look at the iHub board from 2-3 years ago, you will see what I mean.It is a site intended to sell shares, it is fairly obvious. If you look at the numbers of posts by the top posters, you will see this is true. positive bullshit posts far outweigh any attempt to post objective opinion.
Now, I look at iHUb today and I somewhat agree with you. Some of the negative posting is just as tasteless as the positive pumping we have seen to-date. I am not a fan of personal insults, name-calling, the publishing of personal information, any of that stuff. And yes, the negative posting on iHub right now is a disgrace to those that post it.
