Why does no one but me use SF311 ?

Yeah i am making 95 ppercent of the tweets and 99 of the graffitweets to SF311. And it works great. Is the technology too hard for most people? Lack of awareness. Lack of civic sence? Do people want the graffiti? Is making these reports the same as Vigilantism as first wrote the the headline? Should I question if making graffitweets is something that is viewed as unpopular with the type of people who embrace technology in the Mission? Does the twitter crowd want the graffiti and oppose cleaning it? I dont think so, but the fact is no one but me is making graffitweets in the Mission and everyone has a cell phone.
