@dragoncrown @chindit might just be because some people don't like boosting things when they're told to. Kinda feels like it clutters other people's feeds, like those "click share or you will have a bad day tomorrow" Facebook posts.
Tricky thing with this too is it's hard to compare boosts to views, like on a poll. Though if it were a poll, it would be disheartening to see anyone at all disagree.
In any case, I'm boosting it, but I still don't like being asked to. Won't do it if I see it again.
