I think its a way of venting frustration. when you have other sheety stocks that have busted your balls, its a feel good thing, knowing your not at a loss with another, and its nice to rub it in via the odd useless comment or two.
Lets face it, we all look at other stocks and witness the dire situations of others, but not everyone feels the need to make useless comments. As i said before its a "venting" thing.
