Actually Joseph used one of the soundest research methods I know of. He published an obviously flawed "Strawman", didn't pretend it was anything it wasn't, and the wisdom of the group began fixing errors and filling in blanks. So, just like "Nail Soup", a basic seed is evolving into a matrix that has more information than any single one of us could contribute. Thanks for taking the initiative, Peter. -----Original Message----- From: Joseph [mailto:jlhurtado / gmail.com] Sent: Sunday, September 10, 2006 2:55 PM To: ruby-talk / ruby-lang.org Subject: Re: Real World Scalability and Ruby - Top 20 Friends, As Tim Bray suggested I've made my best to drop the guesses on the list, and show only information I know is either true or reported by some credible source.
