I've got a handful of domains, non of which are really related to any specific topic other than one that is a myspace resource site. So I'm wondering how many domains everyone has at their disposal. My main concern is using a domain for an affiliate offer, for example the youtube/ringtone thing being discussed. If I watermark a video on youtube with a ringtone offer, it seems lame if the url in the video doesn't have something about ringtone in it. So, how many domains do you currently use that are niche targeted for specific projects?
