I just came across a link over at Shelley's titled ... Query Shark.
I'd never seen this one before so went to have a look. And my question is - IS it or ISN'T it her?!

I totally pinched this link from Barrie. It's a tribute to the one and only Miss Snark by Patricia Wood. Miss Snark pops up in the comment trail - what fun!
