Ugh, I hate these graphs. Cumulative graphs make even moderate or bumpy growth look predictable.<p>I guarantee the company KPI here is acquired users / month, not total users. Look closely: January 2013 was probably a kind of scary month. October 2012 was awesome ... and they didn't repeat it until 2 years later.<p>This is great for investors and the public, but you can't drive with this graph.
