Is there a reliable source for the latest number of page-views stackoverflow.com receives (not the Stack Exchange network, just that site)?
I need a source that I can cite on my research paper.
Perhaps the most accurate figure would be the one reported by Stack exchange itself.
For example, SO currently reports 5.5 million visits per day:
Also note that sites link Quantcast, Alexis, and even Google analytics are blocked by many user's Adblock and script-blocking extensions. (The reported stats never agree with my server logs.)
Update: At last report (3 years ago), Jeff said that SE's traffic stats come from the Google Analytics API.
You can find aggregate traffic statistics for all Stack Exchange sites on Quantcast.
