Disrupted to death, by sites like Hacker News. Ironic then the outpouring of sympathy on this comments page. I loved Dr Dobbs but must spend at least 10x more time on HN or SO than there, ironically again, sites which are light or zero on advertising, and make their money obliquely (HN by pumping Y Combinator's VC business cred, SO through focused ads targeting developer recruitment). I guess the lesson is that interaction is where it's at. Static content is dead.
Not so sure. I personally love HN (I normally use a different moniker). In many ways, our recent success is in part due to HN and Proggit, which would drive readers to some of our articles. And, of course, it also gave us no shortage of feedback on the articles themselves ;-)
