Yeah, this is a good idea. There's one guy at my previous job that invites all former coworkers to hang out at a bar a couple times a year, and we get together and catch up. Not too many, just about 10 people end up showing up, but it's enough. I haven't used it for a new job yet, although it did get me an interview.
