Nice list, but here is a list as to why it concerns me:
1) Pumper Posts like this smell desparate.
2) Pumper Lists like this get posted before a stock is heads lower.
3) Basher Posts smell overconfident.
4) Basher Lists get posted before a stock heads higher.
I bought on the FB agreement change. It felt to me like all the tweets were misreading the news and failing to look at the upside. Half the Twitter Tweets focused on FB building games (which FB is not going to do).
Today's announcement is one example as to why the agreement had to change.
Now, I have to look at the Bash to Pump ratio again. Yahoo boards, like Twitter, are great contrarian indicator. Hope I find more bashers than pumpers!
