Absolutely, in fact:
Wikipedia is absolutely open to absolutely anyone contributing to absolutely anything! As long as you haven’t been banned, or the article you’re contributing to hasn’t been locked, or there isn’t a group of people waiting to delete anything you write, or you don’t make the same change more than three times in one day, or the subject of the article hasn’t decided to send scary lawyer letters to Wikipedia, or you haven’t pissed Jimbo Wales off real bad. It’s all about freedom.
The Wikipedia philosophy can be summed up thusly: “Experts are scum.”
I just thought to share with you the above quotes from The Wikipedia FAQK by Lore SjÃ¶berg.
