Ignoring the self-involvement inherent in the article, if you want to contribute to something big (There's nothing wrong with wanting that sense of "I helped build this"); go contribute to a big FOSS project!
Fix a bug in rails[1] or django[2] (Pretty sure I saw you're a python guy).
Fix some of the hilarious problems with Bower[3] (Saw some js too).
There's an entire world of awesome problems to solve. Go solve them.
