(They didn't mention blogging.)
This article has it all wrong.
It's not wasting time or slacking off! In my case, it's called being productive and working efficiently! I think I could do everything my job required of me (and more!) and still have time left over.
Our culture states we have to work an 8-hour day, 40-hour week. I think if we all worked 6 hour days there would be a lot more love and a lot less waste.
