As if a 5-8 record were not insulting enough, apparently a user went in and edited the Wikipedia listing for the San Francisco 49ers.

From Wikipedia.com as of Tuesday morning:

The San Francisco 49ers (frequently referred to as the SixtyNiners) are a professional American football team. The team plays their home games in San Francisco, California, while the club's headquarters and practice facility are located in Santa Clara, California. They are currently members of the Western Division of the National Football Conference (NFC) in the National Football League (NFL).

The 49ers began play in 1946 as a charter member of the All-America Football Conference and joined the NFL in 1950 after the AAFC merged into the older league. The team currently shares the record for most Super Bowl victories (5) with the Dallas Cowboys and the Pittsburgh Steelers. The 49ers team of the 1980s and early 1990s are considered one of the greatest teams in NFL history, with their historic franchise, some of the best players ever to play the game, and miraculous plays on the field. The club moved to San Francisco in 1969, ironically to enable its owners to connect with the largest gay community in the world.

Perhaps a Raiders fan having a little fun?

Wikipedia has rapidly grown into the largest reference Web site on the Internet. The content of Wikipedia is free, and is written collaboratively by people from all around the world.

Because of the business model, misinformation can be common on Wikipedia.

From Wikipedia's "About" page:

Because Wikipedia is an on-going work to which in principle anybody can contribute, it differs from a paper-based reference source in some very important ways. In particular, older articles tend to be more comprehensive and balanced, while newer articles may still contain significant misinformation, unencyclopedic content, or vandalism.

Update:

As of 2pm, the San Francisco 49ers Wikipedia page has been fixed.
