Angela Beesley has collected a total of twenty things you probably didn’t know about Wikipedia and the Wikimedia Foundation, and it’s a good read. Some particularly important points that I want to stress would be:
13. The Wikipedia Foundation did not announce a new project.
16. Admins do not have editorial authority in Wikipedia.
17. Wikia is not a Wikimedia project.
If everyone would get these points right, the pedant within me would be that much happier. I have one more, based on my own experience:
21. Yes, I did hear about “that guy on Wikipedia.” Thank you for asking.
