Here you go! Can manage interests under Collections, and open individual hashtags as dynamic feeds, or the whole list.
Two notes: Hashtags in posts will link to search, not this dynamic feed. I'm waiting for feedback what users would prefer. I think hashtags anywhere in event should be similar to the video, right? I'll probably change that tonight.
Also perhaps an option to select your interest set directly from Feeds, though I need to find a way to integrate in the UI as it's growing with options there already. Thanks for the feedback!
