You can follow hashtags (at least on Amethyst). See one like #asknostr and just click on it to follow. It really made my feed more lively, loving it.
Have you got any nice tags to recommend?

If you like rockets, I recommend following #starship
Awesome 👏
You can also quickly filter and zero in on hashtags by tapping the "All Follows" text at the top and choosing the hashtag you want to focus on.
