Very often, people post answers that are wrong, I hate that.

Very often? What is your definition of very often?

In my experience the number of right answers I've seen to questions far outwieght the number of wrong answers I've seen. If you were going on about wrong questions I'd be right there with you.

The few wrong answers I've seen have have been dealt with via the experience system or by follow up answers contradicting them. There certainly are monks here that won't hesitate to point out when someone is wrong. Some more harshly than others.

I'd also rather see a wrong answer to a question than no answer at all. Although if I don't know the answer to something I'm not liable to post a follow up if I am not sure of my answer. Still a wrong answer can be an opportunity to learn.

How can you learn from a wrong answer? Well... first off if you know enough to know that an answer is wrong then follow up yourself and point out what is wrong with the answer and post corrected information! This provides us all an opportunity to learn something.

Lastly, you never know your own perceptions of an answer might be wrong. You follow up with a post and say "NO! Grass is orange!" and you can be sure you are going to find out in glorious detail that no, grass is green. Unless it hasn't been watered in a while... and then it's brown. :-)

Anyway... don't get too bent out of shape if you see a wrong answer. Post a correction and let the exchange of information, knowledge and ideas happen. That's what makes PM so great!
