I'm going to start a project, and I was about to buy the domain when I found out nearly all "normal" domains are taken.. So I have a few questions about internet marketing.
What kind of URL is the best? X = word 1, Y = word 2
www.xy.com (while having some letters written in numbers)
www.x-y.com (both words with a "-" inbetween)
www.xy.net (having the ment-to-be URL, but as an .net)
