Russell Shaw raises an interesting point about a problem with Wikipedia being the fact that links expire. I know someone who words for a rival publisher and this company makes an encyclopedia as well. This person’s job is to scan for dead links and links that turn into porn sites. Apparently this is a bigger problem than most people realize. I suppose Wikipedia links will eventually be found to lead to porn sites as well. When this happens we will see scores of articles about the free encyclopedia’s credibility. Probably just a matter of time.
