The last thing the world needs is more pundits. Pundits only add ephemeral commentary to the world instead of anything concrete and real. They don't materially participate in the construction of any lasting artifacts; instead, they passively observe other people's work and offer a neverending babbling brook of opinions, criticism, and witty turns of phrase. It's pathetic.
Jeff Atwood is right. Perhaps in an ideal world, the only people allowed to grow an opinion are those who also create. Then a pundit's raw opinion will be tempered by the knowledge that they too will be judged.
Until then, we have the real world...
