The first experience for new users to the English Wikipedia
Fragment of a discussion from Talk:March 2011 Update
There are still quite a few people who go around cleaning up articles. The bigger difference from those halcyon good old days is the sheer number of newly created articles every day that are hoaxes, corporate spam, personal vanity pages, and articles with the sole purpose of attacking people. After a while, those who do cleanup can get a bit trigger happy, understandably so.
In a way, Wikipedia is a victim of its own popularity. Everyone who uses Google sees Wikipedia articles showing up near the top, and decide that it's a great way to promote their company, band, career, friends, or just have some fun.
