haha don't be sorry. its been a few weeks and i haven't really developped it much yet. In april(first month it opened) it recieved 600 approx uniques in 26 days. Is that good?
SportsColumn.com would be the best. I would say low $xx to mid $xx right now. The hyphen and the fact that it's Sport Column not Sports Column devalues it.
But if you develop it get some PR and revenue the value of the name will rise.
