Wikipedia (www.wikipedia.org, see link below) is a free online encyclopaedia to which browsers can add or edit content.

Thus there are articles that display some bias (i.e. the repeated posting of Tony Blair is gay on the Tony Blair entry) and others that may be factually innaccurate. Also, some areas of mroe obscure knowledge may be absent whilst other areas that correspond so someone's fanatical enthusiasm may have far more detail than the 'average' user will ever want.

I really like it as there are easy links within articles to jump to related articles and find out stuff about random topics you never would have thought of looking up.
