I have some 20 names or so that I have been holding for 3 years. I believe in some of the names extremely, but none of them have received an offer or any interest from an end-user. Never marketed to domainers. The names mostly comprise of the following: Around 12 .COMs Around 6 .CO 3 .NET The point I am trying to understand is, when do you figure out whether to keep renewing a certain name or drop off and move onto new names? What are the factors that can be considered when making such a decision, when I clearly have one indication that in the last 2 years, none of these names received an inquiry.
