GI's opened registration for the GamesIndustry.biz Network, a trade social networking "thing" that plans to get you together with other games professionals. Provided you're a games professional, obviously. From the site:
Unlike other social networks, it's not just about talking to your existing contacts. It's an opportunity to get in touch with new people across the globe to create genuine business opportunities. The general public cannot see what is happening within the network and you can be sure that the contacts you make will be relevant to your business - the business of games.
