I love the different charts that silicon valley gossip site Valleywag creates. Having just moved to San Francisco, they’re my number one source for the unique world and culture of technology that exists in the bay.
I like how the simple (or not so simple) chart above portrays three different wavelengths/lifecycles of some of the most talked about companies in the technology space. The group at valleywag are a sarcastic bunch, so they manage to mock corporate culture with some subtlety. Fun perspective.
