John Gruber jumps ship

The equivalent, in podcasting news, of Conan O'Brien leaving NBC for TBS

FORTUNE -- On Friday, Daring Fireball's John Gruber, one of the most influential Apple (AAPL) commentators on the Internet, began the latest episode of his Talk Show podcast by launching without preamble into a riff about Andy Pettitte's return to baseball.

No surprise there. Gruber's podcast style is as idiosyncratic as his widely-read blog, and he'll use any excuse to talk about his beloved Yankees.

What was surprising was that after nearly two years and 90 episodes with Dan Benjamin's 5by5 Network, Gruber was podcasting from a new venue, Mike Monteiro's Mule Radio Syndicate.

In the absence of an explanation from the principals, the blogosphere rushed to fill the void with speculation about what had just happened; there were hundreds of posts on Hacker News alone. Among the theories put forward overnight (and collected by the candler blog's Jonathan Poritsky):

• A falling out (believe it or not) over a pre-WWDC batch of Talk Show t-shirts
• A dispute over the division of proceeds from 5by5's new iPhone app
• A disagreement over who owes whom more for the other's fame and prominence
• A divorce after one or the other partner grew tired of their on-air relationship

"I am honestly surprised at how bummed I am about the @danbenjamin @gruber break up," wrote @joshuaaleonard, in one of dozens of Twitter posts. "You guys were my favorite part of the week."

Most long-time listeners wished the new Talk Show well, but the consensus among those who caught the first episode on The Mule (title: "What if the Dolphins Had Thumbs?") was that without Benjamin to keep him on track, Gruber tended to go off the rails.

The iTunes customer review voted most useful Saturday morning pronounced Episode 1: "Unfocused, uninteresting and unlistenable."

Neither Gruber nor Benjamin returned our requests for comment. We'll try to keep an open mind.

Meanwhile, you can hear Gruber on The Mule here. You can get links to his old 5by5 podcasts here. You can hear a clip of Gruber and Benjamin's last awkward signoff here.

UPDATE: Benjamin on Monday posted a four-minute message about the end of Talk Show. He points out that it actually stretched back 120 episodes, wishes Gruber the best with his new show and tells listeners where they can find it. See Special Episode No. 6: Regarding the Talk Show.

  Their contrasting views help explain why Apple's share price is falling while its prospects rise

  Business Insider's Henry Blodget and Asymco's Horace Dediu both watched Steve Jobs' keynote address Monday and both talked about it on Tuesday -- Blodget for 5 minutes on Yahoo Breakout, Dediu for 56 minutes on the debut of his Critical Path podcast on Dan Benjamin's 5by5 network.

  Yours truly talks about Time Magazine, Steve Jobs and a 15-year case of writers block

• Apple data-center dreamin'

  An analyst imagines everything it might be when -- and if -- it opens this spring

  Among the people who follow Apple (AAPL) closely, the massive server farm the company is constructing in Maiden, N.C., has achieved near mythic status. It has become the answer to every unanswered question about Apple's troubled online strategy, from what Steve Jobs was thinking when he green-lighted Ping to how MacBook Air users are supposed MORE

• Apple's 30% tax: The long view

  Another look at the company's in-app subscription rules, this time from 5,000 feet

  One of the things that made John Siracusa's analysis this week of Apple's (AAPL) App Store subscription policy so interesting is what he chose not to write about.

  His essay, "The Apple Strategy Tax," which he posted Wednesday on Ars Technica, neatly sidesteps the emotionally charged tar pits in which so many commentators get mired. As he explained Friday MORE

• The king of Apple talk radio

  Dan Benjamin's 5by5 podcasts are the place to go to hear Mac gurus free associate

  In the middle of a live broadcast discussing Twitter's new president, Google's (GOOG) Android market share and why Microsoft's (MSFT) Windows Phone 7 is a terrible name for an operating system, the guest pauses to ask his co-host: "Speaking of well-hung Wookies, does this show have a sponsor?"

  The guest is Daring Fireball's John Gruber, dean of MORE
