There seem to be two distinct kinds of blogs with highly active comment threads.
type 1: people write comments
type 2: people read other people’s comments and then write comments
You know the first type: full of people who clearly haven’t bothered to read what anyone else said before they rush to the comment box, because they repeat exactly the same moronic/inaccurate assertion that has been made, and answered/corrected, several dozen times already.
Hmm. We need technology that would recognise the duplicated comments and give the offenders an electric shock through their computer. That’d learn ’em.
