I will post a reply from both sides of the fence. I currently own several typos of a famous name. Maybe it was even mentioned in the posts above. However, I realize that at any day soon, I could receive a letter demanding for me to surrender my domain (s), because it is infringing on someone's trademark. I will gladly surrender it, or them. Not only will I do that, but I will also say "Yes, sir". Why, it has already happened to me, more than once.
Then last time, I regged
www.ELoanPay.com . As a matter of fact, it is still regged until March 2006. I can't wait until it expires!
www.Eloan.com says I am infringing on their trademark. This is not a typo, but it's the same thing. Sure, I could get a lawyer, and try to fight them. I could say "EloanPay is not Eloan." But why? Why would I want to spend thousands of dollars for a $8 reg? Why would I want to try to fight a big company, who would probably win anyway? What would I gain? Ok, I won, so what? I would probably still own a $8 domain.
It just isn't worth it. Ok, if you get a good typo, and make some parking traffic from it, great! But, realize also, it isn't worth it, if someone wants to sue you for trademark infringement. Especially, if you know they are probably right.
Besides, that is not the true intention of buying domains. It's ok to try and make money, but not in that way. Remember, I said I own some typos too. But, I will give them up in an instant.
