I used to write a lot for Wikipedia. But I eventually got tired of their 'holier than thou' editors, and sermonizing. It started to resemble a giant bureaucracy, and I was retiring from that!
Now Google hopes to do one better. Authors will compete for cash, and will be judged by the minions who click. I am sure that this will be totally authoritative, and I can't wait to do an article on Harperology!
