Replying to [scotscraft]:
Ok, then let's look at it from the other side: how would you feel and what would happen if for example I posted, "Great success; I just signed a one million dollar contract!"?
Would that make you happy? Would it be informative, helpful, thought-provoking or otherwise have a positive consequence? In my opinion, it wouldn't do any good and I would come across as a bragger. Additionally, it would be a monologue, unless somebody decides to chide me for bragging.
Be happy that people complain, moan, etc., because in the end it helps all of us, even if we only get rid of some emotional burden... like in your case with the above post.
