Here are my stats for two of my blog posts that made the front page:

http://syskall.com/how-to-roll-out-your-own-javascript-api-w...

    3051 visits
    00:00:16 average visit duration
    98.9% less than 10 seconds

http://syskall.com/yc-w12-startups-hosting-decisions/index.h...

    3920 visits
    00:00:14 average visit duration
    99.1% less than 10 seconds

Somewhat depressing...

(edit: according to lenazegher's comment the average visit duration stats might not be as bad as they look since my bounce rate was pretty high, ~95% on both posts)
