LATEST DEVELOPMENTS AT McARDLE KIDS. Courtney Knapp says hey, what's the deal with tipping? She's not talking about the traditional libertarian practice of undertipping or stiffing waiters as a way of showing one's displeasure with the election of Obama, but about one of those thought-experiments that make libertarians such a drag at parties ("No seriously, if she were poor, would you have still married your wife? I rest my case! Hey, why did you bring me my coat? It's still early!").

As you might expect, the commenters love talking about this, not because it advances any knowledge (though it does confirm my suspicion that very, very few McArdle commenters have ever waited tables), but because it allows them to tell the world what and whom they think is and isn't worthy of their rewards ("I would certainly advocate dialing back on the number and types of people you should tip [no, holding a paper cup under a tureen spigot does not earn you my change]").

Next she and the kids will discuss why Cali has plenty of peeled-orange vendors at freeway entrances but Connecticut has none, and whether statist policies are to blame.

Later Julian Sanchez writes something thoughtful and lucid about one of Jay Rosen's "What Is Media Bias" stories. The only bad thing I can say about it is: So what? Maybe some monks will uncover these discussions one day, but at present they're completely drowned out by hollers of MSM LIES! And McArdle's page is about the last place on earth they may expect traction; it's like reading The Consolation of Philosophy to howler monkeys.

Tim Lee talks about interchange rates and the prospect of new regulation of same (unsurprisingly, he's against it), observes that picking a side between merchants and banks is a mug's game. A fair point, though a public that has been serially ass-raped by banks and still ain't shitting right may feel that banks have become a public menace and should be regarded and regulated appropriately.

Lee is not sensitive to this, though; he offers in defense of the banks the fact that his bank gives him 1 percent cash back on purchases and interest free loans. I wonder if he knows that his own failure (so far) to be caught by con men doesn't mean they don't exist.
