And don't dismiss LinkedIn! It's a rolodex other people keep up to date.
Log on once a week and like posts by other folks (job posts, interesting articles, whatever). Send a congrats message as suggested by LI when someone starts a new job. Send someone a job that seems like it might be of interest to them when you see it. Post something you wrote/built/read about.
The goal is to keep in touch so that when you are ready to start looking, you aren't starting from ground zero.
