Domain Age is one thing I have considered. That could be it. I purchased EventCatering.com, Videographers.net, and BanquetFacilities.com. 2 of the 3 from BuyDomains (you can look them up in DNJ).
Right now I have .TV and domain age as the two most likely differences that would impact this.
However, if domain age is the key, the result is the same. I will need to stop investing in .TV and move back to buying .COM and .NET from BuyDomains and other sources to achieve what I need. Not b/c .TV is bad, but newer than comparable .COM and .NET
Our domain budget for 2008 is currently 100% dedicated to new .COM and .NET purchases, while maintaining our .TV portfolio status quo.
I also bought TermiteInspections.com, so that one will be interesting.
You wanted to know what an end user thinks. This is my thought process - in real time.
