Yes, I'm quite a regular London theatre-goer and I have to say she hardly ever posted anything about theatre itself, or that made me think she was in theatre circles and knew what she was talking about. Her general commenting audience didn't seem to know very much about London theatre, so her vague statements were accepted at face vlaue.
She claimed not to know who Tom was before 2011, when he was quietly generating buzz within the theatre world long before that. It's quite a small community, so people tend to know each other - that seeemd odd. But then her whole attitude towards Tom is strange - she's not a fan of him, yet runs a blog off the back of his fame, which mainly talks to and about his fans. I can believe the 'not a fan' bit becausse she rarely displayed any interest in his actual work, she seemed more interested in stirring up drama and petty arguments among fans.
