Go to Wikipedia to read the history of Craigslist
I have read several places that the entry there is maintained by Craig Newmark himself.
Check out the Wikipedia entry at http://en.wikipedia.org/wiki/Craigslist
There is also a Craig Newmark entry at http://en.wikipedia.org/wiki/Craig_Newmark
If you are going to use Craigslist, you better start by trying to understand the innovative ideas of its founder. He defies the big money Internet players, by keeping advertising off his system. He only charges a small fee for posting jobs and apartments in a just a handful of cities. Thanks Craig!
