I would sell the domain if a significant offer were made, but, I consider it very valuable to me and have turned down offers in the low 5 figure range.
I have met people on many occasions (ski lifts, airports, etc.) and told them "internut.com" and without writing it down, they contacted me later, so the name sticks in your mind. In fact, I'm guessing that you wouldn't be here if you didn't think so.
If you want to make an offer, consider the following:
A full page in the Wall Street Journal is close to $100,000. 30 seconds during the Superbowl is 10 times that.
Since I put a "this domain for sale" link on my site, there have been 2-3 hits per day. People are looking at this domain. Eventually one of them will make me an offer that will seem worth accepting.
