Do you believe in and trust Wikipedia?

I love wiki, I've learned so many techniques by reading wiki articles that are detailed enough to give me a grasp of what the author is talking about. Before wiki it would take me hours to find detailed rich links, though I do admit there are a few articles I've come across that just don't make any sense or are obviously written by someone who has a very weak understanding of what they are talking about, luckily those are fairly rare. That makes me wonder how they get approved by wiki strict moderators

It's also nice to read wiki articles about historical events and cultures, you get some really interesting viewpoints and opinions you wouldn't have considered before.

Sometimes it's wrong, but usually it's right. Sometimes when looking things up on it, I find things that are wrong. When I do, I fix them myself. Most of my fixes are just copy pastes, but sometimes I've changed things that are factually wrong, or added things that are missing but worthy of adding.

There are thousands of people who do the same thing I do -- fix things if they find them wrong. That's why it's right so much of the time.

So how is it that, when I look up something on Wikipedia because I don't know it, I'm able to find things that are wrong? The reason is that almost every article I am likely to read includes both things that I already know and things that I don't know until I read the article. When I'm reading for the things I don't know, I am able to find mistakes in things I do know.
