I'm sure that liveblogging Eurovision allows you to make some terrifically sophisticated points, but why bother? If you turn on one of those also-ran channels that you get on Freeview at almost any time of the day, you can find a cultural artifact that is - to the power of about five squillion - much more debased than anything Eurovision will ever give us.
(update: Twittering Eurovision is the new 'water cooler moment', apparently)
But, for some reason, we don't subject it to the same ironic cultural cringe that we reserve for the Azerbaijani entry.
Take this; seen this morning on the David Hasselhoff's Top Fifty Power Ballads show (on one of those channels between BBC4 and E4). Probably the most objectionable four minutes of TV that I've ever watched.
