Well. The first thing that popped up in my head was a fun arcade site. If you develop it, it could be a mid xxx domain. Undeveloped I would say low xx.
Same here, with the arcade site. I'd have to agree with ProgMania with the price, too. Developed, with a lot of traffic, a good arcade site with decent traffic and unique content could probably give you mid to high $xxx. Undeveloped, I couldn't see you getting more than $40 or $50
Well, it is developed, Im currently working on getting my traffic stats up (not bad for now though). Yeah, it's just a fun blog...
