The tracker shows adoption sitting at around 0.5-0.7% yesterday until beginning its upward march upon the public release. While analytics data is difficult to compare between services, last year Chitika found 3% of Mac traffic coming from OS X Mountain Lion as of 48 hours after its launch. Unsurprisin
