A couple of years ago I blogged about The Author’s Big Mistake which is, for those of you who don’t know, replying to a review with anything more than “thank you for your time”.
If you want to see why it’s such a bad idea for a writer to comment on a review, read this book review and the comments which follow. It quickly turned into a pile-on, and was very unpleasant: but the author’s reaction had a lot to do with that.
[We're having problems with our power supply at the moment--we don't have one!--so I might not get back online for a day or so. Please keep comments here respectful while I'm away; I don't want to see a similar pile-on when I get back, but won't blame you if a certain amount of gobsmackedness creeps into your remarks.]
