2. PJ's analysis might have been useful in the SCO days, but really, her knowledge of other topics that I'm more conversant with (specifically, patents) was woefully lacking. Not sure if she'd have done any better with antitrust laws.
For instance, I enjoyed the essays by PoiR, which made a lot of germane references to case law and CS theories, but their premises had tenuous connection to legal reality at best. Or guest posts by mrisch, an actual legal scholar, whose posts were rewarded with comments no better than Slashdot, drowning out any thoughtful conversation. And even then, how many such essays were ever posted? If you thought most of the stuff posted there was good "signal", it probably just means you are not familiar with the legal aspects and enjoyed the content because it appealed to your biases.
