@trwnh @julian @mike @hongminhee @thisismissem @pfefferle @michael @renchap we don't really have a way of knowing what activities our followers are interested. In fact in the general case that's impossible; if I started using a music suggestion system based upon my friends listening habits today, I'd like to be able to use their historic listening data that they have been broadcasting to seed it.

Alternatively, consider that I decide to make my listening history public and it hits a relay. My as:Listen activities are going to absolutely carpet bomb the federated timeline.

Aside from the Annointed Two (Create, Announce) we really need to treat most activities as ephemeral and largely unimportant
