I’ve recently started going to Python meetups. At the last one I attended, the technical presentation was given by the CTO of a local startup, and he made sure to let all of us know that he was hiring. At the one before that, another startup covered the tab for the post-meeting trip to the pub, and somebody from that startup passed out postcards encouraging people to apply.

I have no idea how effective the technique is, but the principle seems sound: everyone at the meetup can be assumed to have interest/skill in Python, and this way you target them without opening yourself up to being spammed by job-seekers who are desperate but not competent.

If you are in an area with ample developers and/or students, try a hack-day with prizes.
