Pretty much just more awareness and eyes on the stock.
I'm interest as I want to compare it to the recent Cohan report.
A lot depends on if the group is respected for their opinion or known for P&D. But either way it usually brings more eyes on the stock and if the stock is doing well then it can be a good thing.
Not a heck of a lot. These reports add very little value. They help get more eyes on us, but the DD done on these boards adds much more value IMO. Good investors usually don't pay much attention to these reports.
