## `contact.async.follow`

`(id, cb)` - follow feed with key = `id`


## `contact.async.unfollow`

`(id, cb)` - unfollow feed with key = `id`


## `contact.async.followerOf`

...


## `contact.async.block`

`(id, cb)` - block feed with key = `id`

`(id, cb)` - unblock feed with key = `id`


## `contact.obs.following`
