I've got addicted to Wikipedia. I try to control it, but it's so fascinating.
Wikipedia is a free encyclopedia. Free has a double meaning:
- it costs nothing (it's on the internet, and can be freely read)
- anybody can freely change its content, or add new items.
If the first point is quite clear, the second one needs some explanation. Yes, anybody can change any single comma of any item of the encyclopedia. How? On the top of any page (even on the main page) there is an "edit this page" link. Click on it and start adding whatever you want to add.
But. But what if I delete a portion of text, or even a whole page? What if I just add some crap?
Yes, any of this is possible. But remember: you are not the only one working on Wikipedia. There is a lot of people working all the time there. And any change is tracked. It won't take a long time that someone will notice the changes you've made, and will process it. If you add some crap, there will also be some automatic bots which will identify it, and rollback the page to its previous version.
However, as an encyclopedia, you might not be enterested in adding anything, but just reading it. Well, it's for free. Just try not to get too addicted.
I am mainly working on the Italian Wikipedia translating pages about Finland. If you're interested, you can have a look at the Italian Portal about Finland. If you don't speak italian, you might like to have a look at the English version of it. Wikipedia is almost in any language!
