We went through the same thing with email. E/SMTP eventually won, but it took a few years for the dust to settle. There were roughly the same number of competing factions. Those that embraced E/SMTP even with its flaws tended to survive, and those that didn't are lost to history. This time around I find myself in a competing faction; but I do know how this story ends. And I also know that E/SMTP is on its way out because we ignored the criticism of the competing factions and never did adequately addresss the identity and spam issues. It had a good run, but I think we're doomed to keep doing this until we get it right.
