When I say "dot com" I often think of the great job that Yahoo did in advertising their site back in 1999-2000 with the yodeling, the trailer in the desert and the chorus singing "dot com"
I find it irresistable to sing my own domain name with that "dot com" ending.
.com is king but with good marketing any extention can be great.
I see .net and .info advertised on both cable and local channels pretty regularly.
