She has the easiest sardonic wit. One which reminds me of several people I love. I always enjoy reading her website. I think that she's kept her head brilliantly through all of the outrageously overblown fame and the accolades... and I'm sure that is helped by those who choose not to go with the trend (which, by the way, has been happening since Novels first started - the only difference is that this is on a much larger scale). I also think she probably feels like many of us feel about all of the hype.
So yes, in summary - Jo rocks.
P.S --- helped by the fact she clearly loves 'Allo 'Allo. I bet that's still being rerun there, huh?
