BUT I do think conferences can be valuable. It really does get you SEEN and your name out there, if only to the people you run into, see your panel, or chat up in the elevator. I was glad to see my three last books at several venues in the book room and I got a nice invite to speak at a local Sisters In Crime event, TBA later.
So was it worth the money? I think, from viewing the crowd, that quite a few people thought not, but, as I already confessed, I really went down to see my children and grandchildren, so it worked out fine for me, with enough PR to make me feel nice and business-like!
