@extinct Bingo. Tried to highlight this in a tip earlier.

"Faves" = "Hey I saw this and liked it". Also with no algorithmic stuff, it does nothing OTHER than thank the author!

"Boosts" = "I want more people to see this"; and are so much more important here since we, collectively, replace the algorithm as curators (and is the only way to get stuff seen on servers it's orgin isn't federated with!)
