The Guardian's Jonathan Jones has written a fine piece on the legendary now 81-year-old artist Yoko Ono's most recent retrospective and her changing critical fortunes (certainly for the better of late). Jones rightly notes how innovative so many of her works that date from 40+ years ago still are, and the importance of her legacy on countless artists. Unfortunately I made the terrible mistake of scrolling through some of the comments below the article and read loads of ignorant and smug screeds attacking Ono in the same old boring, predictable fashion. You encounter (it's not worth it, trust me!) Beatle-fan zealots who "hate her" and seem generally to "hate conceptual art." What truly disappointing stuff.
