Episode #093. Dan Benjamin (Playgrounder, Hivelogic) is back this week. We’ve got a ton of news this week and just maybe an awkward moment or two. Also, I mis-pronounced John Mettreaux’s name wrong, calling him Jake. Sorry about that.

Update: We’re now accepting stories and feedback to @railsenvy on Twitter. You know, if you feel like letting us know about something.

The Rails Envy podcast is brought to you this week by NewRelic. NewRelic provides RPM which is a plugin for rails that allows you to monitor and quickly diagnose problems with your Rails application in real time. Check them out at NewRelic.com.
