Apologies for the Rocketboom obsession but it's become my online soap opera. Anyway, it's supposed to come back to life in an hour but it can't be a good sign when you hit the site, and get a "Site Temporarily Unavailable" message.
Update: No sign yet of anything, although there is a new message that says "rocketboom 2.0...coming soon"
Update II: So, it doesn't look like Rocketboom is coming back today. There a short video of a blank set until what appears to be a baseball catcher abruptly slides through the screen. There's also a message from Andrew Baron: "Rocketboom was obviously very dependent on Amanda's role. Since she left so suddently, I have tried to get the episodes up and running as soon as possible, though I am not comfortable with the way they are going yet."
  I think Andrew needs to embrace the adage: "underpromise and over-deliver" because the more he establishes re-launch times that don't happen, the more disappointed people will become. Unless Andrew comes up with a stroke of brilliance, I'm not convinced it can find its groove again. My advice would be for Andrew to beg, plead and/or bribe Amanda to come back, and let her do the show from L.A. It would make for great PR and resuscitate  the potential of their investment. If you haven't seen it yet, here's a video of Baron explaining what happened last week.
