At the beginning of an essay on "intelligence" and "special knowledge" being hooey that those in power use to invent rational reasons to do what they want to do anyway, Mr. Silber brings up Opera-L as an exemplary mailing list.
With regard to opera in all its manifestations, Opera-L is a staggeringly monumental resource. If you want to know about the bald Latvian tenor who sang Radames in the third set of performances of Aida at the Imperial Inn and Hostelry (in the Performance Annex) in Prstblk in 1907, you can put the question to the list. You'll have the answer within hours -- with sources provided, along with the specific dates of the engagement. If there is conflicting information, you'll be informed about that, too....
It is the "lethal monopoly on the terms of public debate" that groups like Journolist are specifically designed to perpetuate. This is the kind of "expert" knowledge that Ambinder, Klein, et al. are so in love with: the claim to "special" insight and understanding that serves to consolidate and continue the power of the ruling class, and to keep all those "ordinary" people in willing submission. After all, we wouldn't want to challenge the wisdom of our "betters," especially when they are dedicated only to acting "for our own good."Go; read the rest. I have pictures to take.
