THIS!
most of the political/activist/policy-driven discussions on reddit have no impact on the real world and lots of energy is just dissipated into typing that goes in to a db and no further
case in point...most local subs are mobilized against NIMBYs...but NIMBYs tend to voice their concerns at City Council meetings (where it matters), not on the internet...guess who wins?
reddit just takes the energy out of activism and dissipates it
