Whether you're looking for freelance or full-time, there's a site that combines the two monthly HN threads in a convenient format: http://hnhiring.me/

In general I find the whole handwaving "I'm looking for work" approach not very effective. You really need to actively contact companies/potential clients.

With that said, here's a list of resources I resort to when looking for a next thing:
