That seems unfair. Shkreli made the news for doing things that would have a tangible effect on peoples lives, and doing those things with a smile. Let's compare Shkreli raising the prices on life-saving drugs to the first paragraph of Keller's blog post:
>> "I am writing today, to voice my concern and outrage over the increasing homeless and drug problem that the city is faced with. I’ve been living in SF for over three years, and without a doubt it is the worst it has ever been. Every day, on my way to, and from work, I see people sprawled across the sidewalk, tent cities, human feces, and the faces of addiction. The city is becoming a shanty town… Worst of all, it is unsafe."
It's ridiculous and frankly narcissistic the way that he makes it about him and how it effects his life, to be sure. But, his three personal examples (from just this past weekend!) did a good job of driving home for me how interactions with the homeless are different in SF than they are in my area (northeast).
The guy could use a talking to about punching down but I haven't really heard too many people defending SF's handling of these types of issues either so I can't rip him for trying to bring more attention to the topic.
