Naturally, some people think that the way people construct words ands sentences is irrelevant. This is fine. I'm not that fussed either, as long as people do basic things like use full stops. The OP didn't even try. And the raging and swearing didn't really help. If he tried to get his point across in a more polite manner, I'd be more forgiving.
As far as the actual topic at hand goes, we've discussed this many times already. The conclusion was that most, if not all people agreed that constructive critisism is the way to go. But then, no matter how much we talk about it, people will still complain. And complain about the complaining. And complain about the complaining about the complaining.
The only way you can really counter this is by making constructive posts yourself.
