Start with personal pages listed at https://userlist.beakerbrowser.com/ and go from there.

One more question... How am I supposed to come up with that list? I was googling extensively and skimmed through both Beaker's docs and Hyper FAQ. They are friendly towards creators, but I didn't see a word about exploring self-published stuff.

I think it's in a bookmark that shows up on the new tab page in Beaker itself, after installation. Not sure why it is not featured more prominently.
