The tone of the original post does seem a little confrontational, given that Diane has made no secret of her eclectic tastes in her many posts here. As someone who likes a lot of what she likes, I would say she also has extremely good taste! She also comes across as someone who is both knowledgable and hugely enthusiastic about good music - and one who is unwilling to suffer fools gladly.
So, as far as I'm concerned, she's a good egg.
