.com is of course the most widely used, but there others, .net (would be my next choices), .us , .info
If using something other than .com, I would hi-light: sunrooms.net
My traffic comes when people click on a link and IMO they don't care if it's a .com or one of the other extensions. I would suggest a short URL with a keyword or two.I want to get better urls but they seem to all be gone. Is using another url that is not .com a bad thing and which other ones are good to use?
