Here is one example of trademark issue from "nobody". I made a iPhone twitter client called Nukkad (URL: http://bit.ly/Z0uaY
). It has capability to use Google Translate to inline translate tweets. It used to be called Twitter World. First I heard from Google. They wanted me to put up "Translated by Google" at the top of every screen which includes translation.
Next I heard from Twitter, they wanted me to change the name. All issue were resolvable. I am nobody hardly make any money, but yes the big Corporations do go after nobody even if you are not making any money.
