Exactly, I follow a handful of people I know and like and I add/remove a few accounts that I interact with day to day. Don't hesitate to drop someone who is an asshole. (Same advice applies in real life btw.)
If your feed is sparse, look at someone else's follow list and add a few new peeps, but first look at their profile to see if they are active. Lots of accounts just go dead; I guess they don't do the work to curate their feed and get bored.
Rarely, I will plumb the depths of global and find a decent follow. I like to find active pleb accounts in places with the shittiest currencies and send fat zaps. Amethyst auto translate makes this possible. Props to @Vitor Pamplona and all other contributors. 🙌 BTW, any good Turkish, Nigerian, or Argentinian account recommendations?
Zapping and quality replies are stronger signals than likes.
