That's a good question. I checked out some of the people recommended in this thread and saw some things that were absolute cringe. But I can think of some things I enjoy on social media... I like seeing people's gardens and hearing about how they are dealing with problems (pests, blossom end rot, keeping their compost aerobic instead of anaerobic, etc.) I generally enjoy seeing what people create, as least when their ego doesn't overshadow their work. The same goes for people fixing things up. Things that make me think, doubly so if it's not just theories, but is something actionable.
