As an aside, I hate it when a domain owner just sits on it for years, doing nothing with it. My employer is in a similar situation. Our company was once a franchise. The parent company went bust and we bought the name, but somebody else owns the matching Internet domain name, with ALL the suffixes, yet has not had a site for at least 8 years! Likewise, we get no response from the owner or his listed host, and auto-bid attempts have failed.
Someone who makes no use of the name should be forced to release it. We're not going to give him any hundred of thousands of dollars for it, so what's he doing?
As for the topic, it never occured to me to wonder why it's .net instead of .com. Typing gtplanet{CTRL-ENTER} would be nice, but gtplanet.net isn't that much of a strain in excess.
