Wikipedia is not about whining. Complaining about editor behavior is appropriate – at a relevant noticeboard when that behavior is contrary to Wikipedia policies and guidelines and harms the project. But editors should not complain just for the sake of complaining, nor as therapy or catharsis, but to get help in guiding an errant editor back on track with the project's fundamental principles.
If you find yourself complaining more than contributing, it might be time for a short wikibreak to clear your mind, rethink your approach, and help you come back ready to resume building the encyclopedia.
Wikipedia is also not about wining.
But it can grease the wheels, now that you mention it.
Some cheese to go with your whine?
In cases of habitual or sustained whining, admins may hand out cool-down bocks.
Ryan demonstrates correct behavior: he has left the laptop at home, and wisely does not edit Wikipedia at this time.
Incidentally, Wikipedia is also not about wining. A glass of Lambrusco is not a reliable source, too much original research in this area may lead to habitually editing under the influence, and indefinite bocks could lead to an indefinite block. That doesn't mean, however, that the occasional pint can't help reduce wikistress, as long as editors don't become a wikiholic. This can lead to serious problems including wikihomelessness, which is of course the opposite of being a Wikipedian in residence.
