I first used 'pernikety' in this thread. I said that (in my experience) some editors can be pernickety. I don't have a problem with the rules, or the principles, of wikipedia. But there are people who 'patrol' the site, who seem to take pleasure in reversing edits and slapping 'citation required' tags on stuff about which they know nothing. Then there are contributors who write things that are plain wrong, and will revert any correction you make. So contributing can be a frustrating process. But I think it's worthwhile, to share yor knowledge with others.

Wikipedia is not remotely complete or comprehensive. But for some subjects - technology for example - it's as up to date and authoritative as you can get. It reflects the interests of the people who have the time, enthusiasm, and technical ability to contribute.

I use it daily, and regularly contribute funds to it.
