Nice update! I also noticed some visual adjustments in the menus. Looking good!

I really like the idea of the discovery feed. As you already know I'm trying to find some new content creators every now and then and this is could be a nice new way to do so!

Since you wanted feedback; here is mine:

The first post in my stream is my own post :D

You might want to filter these, no?
I also see a lot of posts from people that I already follow. Is that on purpose? There is quite an overlap with the Following feed this way.
Another thing you might want to consider filtering is posts that are already upvoted by the user.
And finally a possibility to sort by "newest first" would be very nice for curation purposes.

Keep up the good work 💪
