This is a top idea, I know people seem worried that there maybe some problems – but you need to look at this from a ‘Risk Vs Reward’ perspective.
The risk is: it might not work, someone might run off with the domain, people might not get the exact exposure they would like on the site etc, etc, now look at the reward, we could get a site in to top positions for gambling terms in many search engines by pooling our resources (existing domains, content, marketing skills). There is little actually ‘Risk’, ok we might spend sometime adding links, generating some content and designing a great site, but the risk is so small and the rewards possible so big that makes it more than worth giving it a go!
if this works for casinos – then roll it out to poker, bingo, blackjack etc.
By the way i’m a qualifed graphic designer with years of experience desiging websites for corporates like MBNA (bank of america) I would be willing to have a crack at the design of the site if needed, or at least help out with any design issue etc.
I have a ruck of casino related domains – some even listed in the DMOZ – should help with the link building etc.
One last thing: I wouldn’t mention the actual domain of the site we choose to use anywhere on forums or boards etc! search engines have a way of sniffing out these things and if it works there will be plenty of jealous webmaster how could report it as spam.
