IFTTT: do the humane thing. add github as a channel.
a). because zapier isn't IFTTT
b) because every coder, hacker, engineer's life revolves around github - it is for each and every one of us that we need an abundance of productivity tools to increase our effectiveness, and maximize time available for hackernews, minecraft, big bang theory, browsing tumblr chicks, stack overflow, checkio, 4chan, and above all, more time to spend on github.
