There's a number of ways to discover folks worth following, but I will give you how I usually go about it:

Hop over to coracle.social, login using your browser extension of choice, and then head to the settings. Under "Content" there will be a slider for Minimum WoT score. Crank that baby to 10 and save your settings. Then head back to your Feeds and select the Global feed.

On ANY OTHER client, Global should be avoided like the plague! But with WoT cranked up to 10 like this, you won't see any spam or bots. You will only see people that would be worth considering a follow, based on who you are currently following, and who they are following vs who they have muted.

If you want to branch out a bit from your current follows, go back to your WoT setting and lower it to 3, then go back to the Feeds and search for any hashtag you might be interested in.

You should find plenty of nostriches to follow with this method.
