Alas, the Foursquare conference, hosted by the Quadrangle PE fund, is an invitation-only affair. And the event, which kicks off tomorrow, is closed to the press except for reporters onstage to interview the stars. And those conversations don’t get released to the public.

That’s a particular bummer this time. Because the Quadrangle guys–who have had a rough year–had the foresight to get a lineup that includes GE (GE) CEO Jeff Immelt, who appears to be in the final stages of selling NBC Universal to Comcast (CMCSA) CEO Brian Roberts, who will also be onstage. Sure would be nice to hear what they say.

Another panel that piques my interest, if only because of the title: “Are Popularity and Profitability Correlated?” It features Twitter’s Stone, LinkedIn founder Reid Hoffman and YouTube co-founder Chad Hurley. And would-be moguls are represented by a start-up pitch panel that includes Dennis Crowley of Foursquare, the superbuzzy mobile service whose name has nothing to do with Quadrangle’s conference.

So once again, here’s the complete list of those you won’t be hearing from this week as they gather at the Plaza in Manhattan. Unless, perhaps, one of my more ambitious colleagues sneaks in–I’m thinking of you, Bobby MacMillan–and gets us a first-hand account.

And who knows? Maybe John Chambers, Steve Ballmer and Brian Roberts will indeed say something important today and tomorrow at Quadrangle’s Foursquare conference. Chrysler’s Robert Nardelli is speaking too. He might have something newsworthy to say.

But you are unlikely to read about it.

That’s because there’s no press allowed at the private equity shop’s annual conference, which starts this afternoon at New York’s Plaza Hotel.

Or rather, there’s some press at the event. But they’ll be on stage. And they won’t be telling their readers and listeners what they saw and heard.

CNBC’s David Faber, Becky Quick and Maria Bartiromo, for instance, will be moderating panels over the next few days. So will the New York Times’ Andrew Ross Sorkin. And network TV news bigshots Katie Couric, George Stephanopoulos and Brian Williams will answer questions themselves (Portfolio’s Matt Cooper will be moderating that one).

Am I crabby because I asked (nicely) and couldn’t get in myself? Nah. It’s Quadrangle’s event, and they can run it any way they want. But it does look like a pretty good gathering of worthies. Maybe I’ll park myself in the Plaza’s lobby and see if I can bump into some of them.
