7 things you should know about wikis

I must admit, I didn't know much about how the wikis work before reading this article. Even though I still can't imagine everything described in this brief article, since I'm not very good at technical stuff, I have gained an idea about wikis, how it works and what it is good for. Many points were new for me: how to change the texts, who can contribute to the texts, how to use it for learning or the origin of the name wiki.
I have understood that it is quite easy to edit texts through wikis, it can help collaboration and maybe the main benefit is its cosmopolitan character and the worldwide spreading.
Some other good reasons for using wikis are given by the author in the beginning of the article: It is for free, you don't need a special software to work with it and you can post on wiki at any time and any place.
