For the suit-wearing business-savvy folk who travel often, IMGuest would be the perfect site for them to catch up with their peers.
IMGuest is the latest social media site to hit the web. Unlike Peer Index though, this site was created specifically for business travelers to network at hotels when they're out of town. The idea is to help people meet interesting guests, set up meetings, create new business opportunities and of course, expand their network. Users can find guests filtered by age, gender and sex, and be informed of their various activities in realtime. Even though it sounds like it's mainly for businesses, the site can also be used and benefit regular travelers.
IMGuest is free and you can sign up simply by syncing it with a Facebook or Twitter account.
