Back when I used to visit Slashdot, it'd be more like a pageview every 5 minutes. The core audience used to be extremely dedicated. I wouldn't be surprised if their pages per visit number is still abnormally high.
Not since the grand redesign(s). It's been pretty much maddening to use for at least a few years, so my readership has gone down from 10+ PV/day to <1/wk. My uid is 115xxx.
Couple this with their editorial mechanism posting the same 30 word blurb for the same news item everybody else is posting, only two days later after every body has said their piece, what's the upside? The commentary there is no better than other places.
