Maybe multiple sort methods to find people you want to follow. Most recent by default, then toggle to most likely people you might want to follow based on 1 degree follow separation count + 20% weighted 2 degree followed by person you follow count. Another toggle could filter people with below X followers, X set by user, default 50. Btw, a simple follow superset like that to replace global feed would be a great feature in general that no client has yet afaik.
