I mean, everybody loves to complain about Muni. Sometimes it can ruin your day. Sometimes, complaining about the bus can make you look like an entitled princess (and Metro riders - I'm looking at you, N-Judah! - remember that over two thirds of Muni riders take the bus, not your train).
Muni can't be everything to all people. But is it serving its purpose well or, to put it another way, is it fucked? A man named Sam Kimbrel put together a clever and attractive site to ask that question: howfuckedismuni.com. The answer may surprise you. Clicking through line after line, I keep seeing the message "not particularly fucked." I do expect that will change from time to time, nothing is "not particularly fucked" all the time. But maybe the buses are alright.
