The Most Engaging Sites on Hacker News

Not surprised to see "Datagenetics Blog" in that list. You can tell there's a lot of research and effort behind every article. It is also one of the few blogs where I'm genuinely learning something as opposed to solely getting entertained. http://datagenics.com/blog (seems to be down now)

Bold claims for such a small sample size. Arguably, someone who would go out of their way to sign up for look mark, tends to invest more time and focus in their interactions with HN; preferring long for content. This ignores the silent majority that don't have a look mark account, and/or don't have a HN account, and/or visit the site infrequently.

I don't know how anybody spends 11,000 seconds on TC, but love NYT and ARS. Also pretty interesting to see the bias in users that use lookmark. Hopefully having your friends use it helps.

fascinating breakdown, thanks for crunching the numbers Dave. a few new additions to my rss reader are in order.

i'd also like to see which articles are returned to most often (ie used essentially as references), so repeat visitors. this could also be a measure of quality. i bet PG would win here hands down.
