kfw--the reason i don't care if dancers Tweet between acts or do anything else that pleases them, is that nobody in audience sits in rapt attention during intermission, meditating on how this might help the continuity of a near-sacred performance.
I understand your points, even if I have different emphases, though. It's much more prosaic backstage, and it's true, even if the performer-pros know that they are indeed making up their eyes in a purely ordinary way to then do something extraordinary, the audience has a right not to want to see that. But it may also be possible that the performers, even if Tweeting, do not subconsciously lose sight of the performance they're in, even if they divert themselves a bit--I think diversions are a form of rest, and that, in fact, you come back to the 'concentrated important stuff' more fortified sometimes. Now that's worth thinking about, isn't it? Although I do think the 'generational matters' are exactly right. That I sympathize with the Tweeters while personally having no interest in it myself is just me. I've watched an old vhs of Garbo in 'Romance' 5 times in the last two weeks and my only interest in Twitter is discussing it here with smart people! I think Bouder's Tweets are boring too, personally, I just don't care when and where she does them.
As for Farrell, she's glamorous even if sometimes 'girl next door'. Her own 'aura', as I've mentioned once before, is much like Garbo's, and I always like this self-possessed sort, that's way too proud of their singularity for some tastes: They are worth emulating for this.
I like the way you handled my provocative post, though, because I fully intend not to give into the internet's encroachment whenever I can (I've been successful thus far in only being wounded, but not mortally). I actually like this peculiar thread, because it does show, I think, a brilliant young artist who acts silly sometimes, but it doesn't get in the way of the important things--and that helps me learn better how to integrate some of this new media that often really does annoy me to no end, and has even caused me real problems. But don't think for a minute that I wouldn't rather discuss some of the Reality TV people on THIS board than have to watch any more of their YouTubes

They were all horrible, no matter how 'inspiring'.
I just pm'd Hans about that Aurora we were discussing along with Lezhnina, I believe it was Dumchenko, that had this seemingly uncanny ability to seem as if she'd been in the role before she went onstage and after she went off. I haven't had that impression too often, but you know, it may be that Twitter, etc, really DO interrupt to a degree, or is it not possible that it's also 'the age of Twitter' that does it? I find that I am extremely irritated by these things even without using them.
And it's true that both Farrell and Garbo (like Dumchenko, if that's the right ballerina), never really lose a certain aura-persona, even though Garbo, in particular, infuriated many people because she was determined to live her life as she chose, not as they chose. But, when you look back, that was a way to make the persona even more inaccessible and mysterious. Yes, I'd have to agree, if you can still pull it off, DO IT! I just think the opportunities for this are less and less, and I don't think NYCB has any mystique itself anymore. I don't think people want to hear that, but it's not really any worse than saying 'Bouder is exciting, but has no mystique', esp. since she's probably the best thing in the company. But, while I do think some of this mystery and aura may still be found, I do think it's diminishing. Yes, of course, I don't like it either, but I've GOT to learn to be more sensitive to young people!
