Since starting at Puppet Labs four months ago, many friends have asked me why. "Puppet is a systems tool, right? Isn't it all command line? Where's the user experience? Don't you usually work on the web? Are you designing their website?"
To the contrary, I'm happy to say that for the first time since the Internet was invented I'm working at a company whose web site doesn't need much of my attention. We have fantastic people working on it already, and I think it's quite good.
