Which is your preferred way to contact new leads/partners?

Hey, Hunters! Hope you are having a great work week :) Today I wanted to ask you about your favorite way of reaching out to different people; like potential users or partners. For example, at ReSkript we mainly use Linkedin; by reaching out to small-medium-sized team members. And we also use Product Hunt a lot, since it's very easy here to find like-minded people who belong to different areas.
