I utterly despise Wikis, especially Wikipedia which has wrong answers on about half the stuff I look up. When the article looks especially bad, I reach for my 80s vintage Encyclopedia Britannica for the correct answer.
Please don't get anything Rockbox near Wiki. Especially with RockBox, anything posted to the site must be proctored to scrape off the errors. Letting just anyone make edits is the path to as sorry a product rife with errors as wikipedia.
