Many people in EA value personal productivity highly, and make it a goal to complete as many tasks on their to-do list as possible in a day. Some people (myself included, in the past) seem to tie up their feeling of self-worth with how productive they felt that day.
I think that increased productivity should mainly be used to reduce the amount of time we work each day, and not to get more things done. To live a truly fulfilled life we need more unstructured, unproductive time when we can be ourselves and do the things that we find inherently valuable and enjoyable.
Here are some things that I find valuable in themselves, and not particularly productive:
Running along a river or canal in the morning
Reading a history book in a café
Listen to classical music on the radio
Prepare an elaborate dinner for my girlfriend
Try all the different types of cheese from my local shop
I second Lukas's thoughts on how this post could have been more useful. In addition, I haven't seen much evidence of the phenomena discussed by the author (those people in EA who I've met tend to be fairly productive, but basically all of them also have hobbies and enjoy doing silly/non-productive things on a regular basis). More numbers, or even a couple of specific anecdotes, would have been helpful.
I also agree with the meta-meta-note. Unless someone explains that they downvoted because they disagreed, it seems healthier to assume that a downvote indicates displeasure with an argument's presentation, rather than the associated opinion/subject matter. Few communities are more likely to say "great post, even though I disagree" than this one.
That said, if anyone reading this has a habit of downvoting arguments they disagree with, even if those arguments are presented clearly and with solid data/logic, I'd weakly recommend against doing that; I think the Forum will flourish in the long run if well-crafted writing and thinking is reliably rewarded -- or at least not punished.
(I work for CEA, but these views are my own.)
