I think I would probably opt for following hashtags as a preference maybe. Ideally, feeds/hashtags > accounts.

Just out of curiosity have you used Bluesky (yes I know it's mostly poop) but their feeds are very slick and useful.

Eg of hashtags # Asknostr, bookstr, meshtastic, (maybe quite niche, but nostr seems to attract a lot of enthusiasts), movies 🤔🤔 hmm it is actually quite tricky really, (probably not a good sign that it is as tricky as this lol)

Off the top of my head, seeing as you asked specifically about accounts... I would add accounts:

I'd also probably trim a lot of what you have (not going to name lol). And yeah, I think I would reiterate to click follow rather than have them autofollow as default and press unfollow. I think on sign up you want to get to the end as smoothly as possible and end up saying yes to everything and then getting annoyed about why a client would recommend accounts of little value.
