Follow things

When you follow something, you'll see updates to that thing in your Activity feed

Follow page we should highly incentivize this, very granular, very good

Follow group this could be rather noisy, we could default to fewer pings than following a page

Follow user this won't be allowed at all. Users should be allowed to have diverse interests without souring parts of their audience.

we will show Follower count , but we won't show following count. You should follow tons of things. You shouldn't have to worry about your ratio.
