I can't really post all that often in this game simply because of the nature of my character; the ship's doctor's main schtick is to react to the rest of the crew, generally by somehow being mismatched with the rest of the cast.  Unfortunately, I can't go yelling "Dammit Jim!" all that often because there's not a lot of posting for me to react to.  (and my character tends to look pretty funny when he acts alone and nobody else posts about it, since he's supposed to be a foil.)
