The HitchHiker's Wiki to the Galaxy (?)

Heh, las cosas que uno lee en slashdot...

Wikipedia has now supplanted the Encyclopedia Britannica in many places as the standard repository of all knowledge and wisdom. Although it has many omissions, contains much that is apocryphal, or at least widely inaccurate, it scores over the older more pedestrian work in two important ways.

1. It is slightly cheaper
2. It has the words "You can copy and edit me for free" inscribed in large friendly letters in the license.

edit: otra forma de la misma idea:

In many of the more relaxed corners of the Outer Eastern Rim of the Internet, Wikipedia has already supplanted the great Encyclopaedia Britannica as the standard repository of all knowledge and wisdom, for though it has many omissions and contains much that is apocryphal, or at least wildly inaccurate, it scores over the older, more pedestrian work in two important respects.

First, it is slightly cheaper; and secondly it has the words "anyone can edit" inscribed in large friendly letters on its cover.
