Which classical musicians are on Twitter/Facebook and what are they doing?

Amanda Ameer, via her ArtsJournal blog, Life's a Pitch, has taken a look at selected classical musician's approach - or perhaps their publicist's approach - to both Twitter and Facebook, with minor mentions of wikipedia. The list includes several people you may have seen on a Celebrity Series of Boston stage in the  past, such as Sarah Chang, Hilary Hahn, Renée Fleming, Lang Lang, Maya Beiser, and Yuja Wang. Lady Gaga is included on the list, I assume for the sake of comparison.

Check out the complete post, Doin' What Comes Naturally.

UPDATE:

Here, in no particular order and for no particular reason, is a short list of other classical musician types that Tweet. I am not endorsing these accounts, and I can't verify if they are who the names claim (hint: referring to themselves in the third person says publicist to me, not that there is anything wrong with that); I bring them to you in the name of science ...
