Sorry, no thumbs up from me. Everyone here has the right to express his opinion and the fact that a shareholder is disappointed is nothing new. Maybe this is the first time you bought shares?
Shareholders buy part of a company because they have faith in a company and if they feel that the company disappoints them, then they will complain or sell their shares. I'd rather have 100 complaining people holding on to their shares than one silent shareholder who sells all.
If you want to make a messageboard a valuable place for people to visit, you should also allow comments that you disagree with, without telling such commenters to get the heck out of here.
