I don't necessarily look at the username, I look at the content of the post and then the username. At times I've been very surprised at the good information that has come form a young perspective.

The one thing that is usually not so tolerated by most is a young one stating facts that aren't so much facts and not willing to learn.

I don't care what your age is, everybody can learn, at any moment, anyone can teach or at least add to the discussion. At times a young perspective is a fresh perspective.
