Yes. That's pretty much what it was. I found it particularly awash with Stupid when that article pointed out the big names who'd come into playwriting sometimes well after the age of twenty-five, which on the whole is probably most of them. Also there's an unsettling comment down the bottom that says there's no point in sending out non-comissioned plays to anyone ever, but I'm ignoring that.
