I found a pretty cool site that seems like it has some potential, and is worth a look if you're interested in online advertising opportunities. It's sort of like milliondollarhomepage but with a twist (I can't believe how well that guy's simple idea was) anyway the url is theonlinebillboard.com, and surprisingly I can't find any other ideas similar to this one on the net (doing google, and yahoo searches)
To be perfectly honest I think it looks tacky and crap. I certainly wouldn't want any of my sites on that. These "million dollar homepage" things have been cloned a bazillion times and have becomes pretty boring. My opinion of course KP
it's not 100% like milliondollarhomepage, the only thing that I would consider similar between the two is that they're both advertising sites, but they're each taken two totally different directions (my opinion). The kicker/gimmick of this site is being able to "advertise virtually anywhere in the world" which I find sort of funny and interesting as well (which makes it also a little more different than million dollar homepage).
