@lambadalambda I'm starting to lean to that thinking as well.
The attractive fiction of the Totally Integrated Internet is that Everyone Has the Same Data. The option with Federation is that /stuff that is worth going off-Instance/ does, /but not the other crap/.
"Worth" is, as always, subjective, but it's indicated by the collective interests of users. An element of "data physics" is the loss of friction and momentum. Organic following dynamics restore some of that.
@lambadalambda It's not just at node-level that the bots have an effect, but across the whole fediverse. Individual follows select for what /is/ considered worth-following. Not perfectly, but at least probabalistically.
OTOH, it can be disconcerting to see a single boosted post from a thread without context. One of @maiyannah's from shortly before I joined was boosted to my Home, and all I see is her comment. Going to HA I can't grab timestamps.
