So I'm driving out to College Station, TX, in March to see you at Aggie Con (oh, well, to see _Aggie Con_, too, I suppose). Could you give us a secret wave that we readers of your blog could make, say when you're climbing into the elevator or passing in the hall, by way of saying, "Hi, I read your blog. I think you're keen!"? And then you could wave back in some way that says, "Hello, Reader of my Blog. Glad you like it." Then we fans could feel like we'd had a little person-to-person communication with a writer we admire, without having to interrupt you as you're going from place to place. ^_^
Anywho, I think you're keen. Thanks for all you give to us readers.
Wouldn't it just be easier if you came over and said "Hi, I read your blog. I think you're keen"? And then I'd say "That's very kind of you, I'm glad you enjoy it," and you could say "Lovely weather we're having" or "It's raining" or "Are you having fun?" and I could say "Yes, isn't it?" or "I suppose I must be," and before you knew it we'd've had a conversation, and the world would be a better place.
I'm not very scary, and will happily talk, unless you catch me at the wrong time (eg. on my way to a panel/signing/the toilets/bed). And it probably would work better than secret signals, which are always liable to misinterpretation. (You, thinks: I have flicked my earlobe at him several times, yet he has failed to respond by tapping his cheek. Perhaps he hates me. Me, thinks: I wonder what's wrong with that person in the third row's earlobe? Probably an ill-fitting earring or something.)
