Wikipedia is; ‘The Free Encyclopedia that Anyone can Edit’.
It means what it says. Anyone can write an entry about anything. And entries can change every other minute.
When Wikipedia first arose in 2001, some folks used it to make ‘official’ entries about fictional characters. One could search for Spock and get a referenced biography.
Aware that Wikipedia was not an authority, many users search a topic get the bare bones and then do a subsequent search, using the footnoted ‘authorities’ or various points raised in the article.
No one with a fully operational brain would accept Wikipedia as is/where is as any authority on anything but fictional characters, the plots of shows, and similar categories.
There has been proof after proof, from famous users learning they were HIV positive or Homosexual, or dead via a Wikipedia article.
The errors made range from the ridiculous to the vicious.
Some are done for fun, just to prove they can be done. Others are to twist facts and push their agendas.
Anyone can write an entry, so one should read a Wikipedia entry as one would any questionable document.
Of course, this implies that those who go to Wikipedia have the intellect to discriminate between fact and fantasy. To understand the warning that Wikipedia posts; that is, that anyone can make a post.
As most people are a bit dumber than Forrest Gump they believe anything posted on Wikipedia as if it is the Encyclopedia Britannica.
