Hey, it worked for MLK, Jr., why wouldn't it work today?
Besides, buses are bad for the environment too! It's just lessening the damage by cramming as many people as you can in it.
In regards to SOPA however, instead of taking the car or buses, people should just stay at home instead. No need to take buses then because nobody's going anywhere. The demand would be "I'm not going anywhere because I can live with just the Internet but if the sites keep 404'ing, how am I gonna eat?"
OK, I was just kidding but boycotting the bus is actually pretty damn efficient of a protest especially here in San Francisco. You see, the bus line here is so complicated that I need to look up which line should I take on Google Maps in order to not get stranded in the next city. Now, if Google is shut down, how am I supposed to get around?
Also about being a leader, you'll get the hang of it once you're put in the position. What you need to realize is that so many a 'good' leader aren't actually good. You know, just because you're 'decisive' and 'responsible' doesn't mean that everyone else feels like they're being 'led'.
Most of the time Gar, the best leader is the one picked by the led. Which is why people are so big on democracy nowadays. Of course, with things like SOPA and ACTA, I don't know if democracy is even a thing anymore.
