Public Status following
It would be nice if it would be possible to only follow the public timeline posts of a user.
This is mostly handy for "polite" bots that only post limited on the public timeline but flood their non-public timeline with full posts. There is little as annoying as trying to follow a bot that appears to only post sporadically (once every 3 hours for instance), but in practice ends up completely flooding the entire timeline because of the non-public posts (which happens every 5 minutes) when followed.
