The idea is to have a single feed people can use to see all sort of "interesting" posts. Excluding already followed accounts will force everyone to check out 2 different feeds every time.

Ah, so will it replace the following feed over time?

This is something we don't have in the following feed either. Will think about it.

I remember having an "Exclude voted" in one stream on PeakD, but I can't seem to find it anymore 😂
It could be useful to have I think. Also in the other streams.
Voted means you have seen the post already.
