The Nieman Journalism Lab at Harvard University posted an analysis of the top 15 newspaper websites. While they have many really interesting charts, they also posted the underlying data in a spreadsheet, which includes, for each of the top 30 sites, for 2007 and 2008, the monthly unique visitors and time spent per visit. Wow - great data (if it's right - which, of course, this blog cannot confirm).
