Not to be entirely dismissed.
Its strength lies in the the sheer number of posters.
I find that if an obscure stock suddenly does something out of the ordinary HC is often the quickest reference since you can bet there is a poster there who is familiar with the stock, has some idea of what's going on, and is keen to tell the world.
Of course what they post may or may not be entirely accurate but at worst the info is worth what you're paying for it

PS. Not a good site for newbies though. Just too many sharks.
