MusicSnob1 -- are you suggesting that BWW *learns* of a show's closing via the message boards, deletes the "scoop" threads, and then publishes it as breaking news? If so, that's ludicrous because generally when a production is coming to an end, it's not "news." BWW has their own insiders and direct sources to get the "scoop" from.
So perhaps the threads ARE deleted because it IS speculation until it is confirmed?
I think in some instances threads such as the "Riedel: RAGTIME to Close January 3?" haven't been deleted because they are discussions about published news stories.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
