Here's an interesting story about the dangers of homonyms. Youtube.com, the online do it yourself video showcase, is being sued by utube.com, a pipe and tubing company. Why? Bceause ever since youtube.com got popular, utube.com has been getting like 2 million hits a month, paralyzing their online website and business interests. They are suing for Youtube to either change their name (probably won't fix the problem), or for Youtibe to give Utube enough money to establish a new corporate identity.

I don't know what the legal issues are on this, but from my perspective, utube.com has a good point, and probably does deserve some sort of consideration from youtube.
