I'm not saying this to dump on you, but maybe if you DID occasionally post positive things, people might pay more attention to what you have to say. I'm sure you have a great sense of humor. But if you always (or almost always) post negative things, people might pay less attention to you because they'll (erroneously, perhaps) think that you just like to be difficult.
I've got no dog in this fight, so to speak, but I thought I'd get in a diplomatic comment before some of the less tactful members weigh in.
