What are lists and feeds? Does anyone know lol?

Feeds are basically alternate versions of your timeline. You can pin them to be able to switch to a different timeline with a unique algorithm as you want to. You can also make your own and share them if you want to. It's a neat feature. I have a couple unique feeds that I follow.

Glad to know I'm not the only one who was confused like this. Kinda sucks as well you can't directly follow a specific hashtag at least from what I've seen

Feeds are post timelines based on topics, lists are post timelines based on specific accounts
