how can certain threads be followed / saved / favored - for later use?
I upvote way too much stuff for that to be useful, personally. I use “boost” as my save-for-later button instead.
what does it do,in comparison to favoring?and where can it be found for-later,if boosted?
Yeah, what FaceBear said, “boosts” are better as a “saved” list. Boosts are unique to Kbin, and currently they determine a thread’s popularity, not upvotes as you would think. That’s supposed to change soon, according to the instance owner (who is a real nice guy btw).
