I have a love/hate relationship with Wikipedia.
As an academic I like it because it is a nice starting point for any topic, but hate it for anything close to "real" research. As a teacher I would never accept Wikipedia as a source unless there were plenty of other sources to back that up.
As a gamer I like it since it usually gives me what I need fairly quickly.
I also like the "every one works together" aspect. But that also gets on my nerves.
Today though the wikipedia community is getting on my nerves. Long story short, some articles I worked on are up for deletion. Not only that, the editor that put nominated them for deletion chose to do it over Christmas where it is likely that he will get them deleted since no one can help me "save" them.
I used to be a very active editor on wikipedia. I even donated money. But it seems more and more that there are some people there with personal agendas to have articles they don't like deleted. I just spent a a couple years waiting for one such person to get banned, and now others want to take up his crusade.
Maybe I'll just post stuff here instead. The audience is smaller, but at least I get the feeling that it would be better received. Though some of the stuff I work on wouldn't fit even the broad range of topics I cover here.
