Software developers are over-represented in general on the internet, and I sort of glazed over and wondered if I was back on Reddit/digg/slashdot/... .

I don't think 'the internet' and 'Reddit/digg/slashdot/...' are really the same thing anymore... Software developers are a disproportionate percentage of participants in some parts of the internet but probably not on, say, MySpace, Facebook, YouTube or many of the other sites with the highest traffic. It is not really true any more that software developers are 'over-represented in general on the internet'. They probably are on this particular site however.
