I've got nothing against someone who is unhappy with a product stating why this is so. Not everyone is tech-savvy, not everyone is in their best of years, and we can all make a bad decision from time to time. Though there is a distinction between raising an issue and railing on about it in unending posts. The "Dude, just get over it!" point.
Having a forum named "Griping" won't work, I guess, because some of those posters actually want to be understood or helped. Someone may post something to shake your head at once, yet be downright helpful the next. Fine with me. We're a community, after all. All for one...
