What Is an Alternative to LinkedIn?

It's hard to qualify what is 'best' without knowing what parts of the site are most important to you, but here are my thoughts. There are some sites or pages that are specific to an industry.

For example, county bee clubs and state beekeeper associations typically have a Facebook group. Facebook, reddit, association/industry websites/forums can give you the ability to create a profile, share information, and connect with others. In-person meetings and conferences are an option too.

Your own website operated under a domain you control. It contains prose, images, and other useful information, created by yourself and available nowhere else.

Build your own platform, not someone else's.
