LinkedIn has been high value to me. You just need to ignore the whole social feed, games, and garbage notifications. Use it as a resume platform and let recruiters / founders reach out to you. I’ve had great job offers in the last few years with basically zero time investment. 3 years ago I +50%’d my salary and went full remote on my tech stack of choice just thanks to LinkedIn. And I absolutely suck at networking and invest no time in it at all.
