How often do you use Wikipedia?

Question for you — How often do you use Wikipedia each week?  I tend to use if at least once a week.

In a recent article they claim that they will soon produce a book that has up to 90,000 authors.  Some excerpts of the article are list below.

A book with 90,000 authors
Wikipedia makes a bold claim that it will make history in print publishing by creating a book with the most credited authors ever.

Among the unlikelier announcements made at Wikipedia’s conference in Alexandria, Egypt, was the bold claim on Friday that the online encyclopedia was about to make history in print publishing: creating the book with the most credited individual authors ever–about 90,000.

The book with so many authors is the product of an unusual alliance – a single-volume encyclopedia produced by the German publisher Bertelsmann from the 25,000 most popular articles on German Wikipedia. The volume will have very short articles, no more than a few paragraphs at most, and include photos and illustrations.
