Before I get flak: yes I know Safari sucks
Here is my two cents: The author mentioned you can't have a social app without push notifications: I hate the idea that everything should be able to grab my attention. Though obviously the support is needed.
But also, Safari is the last browser stopping Google from total market dominance. Firefox is irrelevant. And this is coming from a Firefox user who remembers when 2.0 came out...
I do wish things were better.
