In his old year cabaret show, Peter Pannekoek stated the buttons near crossings don't actually do anything, they're just there to just pacify people.
I'm fairly certain they in fact do work, though for cyclists they're mostly redundant: the magnetic loops in the road surface detect cyclists. Only for lightweight carbon bikes a manual button is still useful.
Am I correct in my assumption?
Good point, valid concern! I hope existing (real) communities (from existing subreddits or elsewhere) can have leaders pointing users to a specific Feddit community. What would be even more awesome, is if communities could be merged: that way we could 'repair' in a sense, fragmentation that happened naturally without losing the users and content that one of the communities already amassed.
