I don't see any links to Foldit's social media on the Foldit website. It's possible that they're posted somewhere, but they should be more prominent. Social media is very important for keeping the community alive and bringing in a steady flow of new users. The current wave of Coronavirus helpers won't last forever.
Just some small simple icons at the bottom of the page should be fine.
Aside from that:
The Foldit Facebook page should have links to the other social media pages.
Every Foldit Youtube video should have links to the other social media pages.
