Where do you go to search for jobs?

Outside of Linkedin, where else do you go to look for jobs? Does anyone use niched job boards like [https://web3.career/](https://web3.career/) or [https://angel.co](https://angel.co/jobs)?

For those of you who use Linkedin, do you ever reach out to the hiring manager or current devs after applying?

Edit: this question is for U.S. roles.
