I actually kinda like this idea. Groups usually make things less awkward. Unless we're talking orgies.
Fantastic idea, but like all dating sites, starting from scratch in terms of userbase will be tough. A quick search shows a total of six "groups" near me, and I'm in a major metro area.
Hope they can attract enough attention from a Match.com-alike to get bought outright.
They need to associate themselves with the Disco movement of the late 70's. That is the general idea. Yuppie "groups" going to trendy places like Studio 54, and meeting up with other "groups". Perhaps letting trendy (upscale) nightclubs to advertise or interface on their portal would be a good idea. Like let a "group" book a room at a club listed on the site. I support the disco movement in principle, or more precisely, I support its revival. But a fuzzy definition like "group dating" doesn't really get me on the love train.
