Funny--he started out "after another Campfire outage this week", I thought the post was going to be about the unreliability of Campfire, its platform (ruby, dash of C, AFAIK), and the uptime issues causing user-hostility amongst 37signal's customers.
Which was going to be (and still is) ironic since BankSimple is likely using the same technology stack.
After being down voted: so Alex can call all AIR developers lazy because they don't want to leave their comfort zone and write native apps, but I can't insinuate the same thing about 37signal's not wanting to leave their Ruby comfort zone to make a reliable messaging app? Oh, right, we hate AIR, but love Ruby. Sorry, I missed that there was a double standard. :-)
