Apparently not...

One of the first times I'd come across
Wikipedia, was actually a link I found here about Schaefer beer. Here's
the first part of the entry (the rest is about Schaefer in Puerto Rico &
its ad campaigns):

"Schaefer Beer is a brand of beer from the United States... SNIP

Wha? The famous Schaefer beer from the F & M Schaefer Brewing Company
of Brooklyn, NY, founded in 1842, had no connection with the above (but
similarly) named Wisconsin brewer... SNIP

Schaefer was NEVER the "best selling beer in the world"... SNIP

Very impressive, but why are you telling us all this? If you
know so much and care so passionately about Schaefer, go
back to Wikipedia and correct the bloody entry.

Now do you understand the concept?
