Nathan Fillion, aka Captain Mal “Tightpants” Reynolds of the Joss Whedon TV show Firefly, has posted in his blog about airplane etiquette:

Your space. Especially for us big guys, flights can be tough because of how little space is provided for our enormous frames. For shoulder space, favor the side that has no one on it. Don’t lean the seat back if the person next to you has if you can help it. As for legs? Avoid spreading them like you got some big business down there. Cross your legs below the knee. You’ll be surprised.

Not a particularly geeky topic, but hey, NATHAN FILLION. Nuff said.

Edit: he’s also got a good article on contacting celebrities online:

Autograph requests: You kidding me? After all we’ve been through, you’re going to cheapen it with “Sign this”? Sheesh. And if you really are getting it for a really good friend who really deserves something really special, then why don’t YOU do something thoughtful and special? Cuz, guess what? You don’t care about that person. You feel guilty because they do so much for you and you do diddly squat for them. Case in point: Your big thoughtful special idea is to put three lines in an email and you can’t be bothered to send a self-addressed stamped envelope (customary for autographed photo requests, some folks include the photo as well). So, you won’t spend $2.50 and a walk to the post office for this friend. How does it then become MY job? I’m an actor.
