Wikipedia, a new concept in knowledge database.

Welcome to Wikipedia, the free-content encyclopedia that anyone can edit.

This is the statement that we can see when we enter its web site. It is a different philosophy to approach an encyclopedia. I heard about Wikipedia about a year ago but I didn't ever go inside. What a fool! It's incredible; you can find great articles about many things. It's free, open and if something is missing we can add information or change it. Yes, we can edit it.

It's crazy but works. We go in, we edit, and we leave. We can call it OUR encyclopedia. It's the first time I realize what does sharing knowledge means. Thousand of people contribute to make it bigger, to improve it, for free since 2001. It's like in Star Trek but now.

By its open nature, vandalism and inaccuracy are problems in Wikipedia. But I will take the risk. Also Google is inaccurate.

If you want information about anything, try this before Google.
