I used to have a rather huge callus on my middle finger from writing; it hasn't come back for a year or so, though, probably because I'm splitting my writing fairly equally between notebook and computer (or maybe it'll reappear in high school, who knows).

Though it's smaller than it used to be, back in the days that I also always had some ink on my fingers from my fountain pen.

I still write a lot by hand. I think about half (perhaps a little more) of the stuff I write gets a first draft by hand and then type it all up. Depending on how much editing I want to do I take pen (for complete scene rewrites) or computer (SGP).

I used to have one, back in school. Came from a combination of hand written work in classes, and a penchant for writing emo poetry which happily I grew out of by the age of eighteen.

Don't have it any more, however. I may have just spent three years doing a degree, but one could get away with taking very little by way of notes, and all work was typed (I've a suspicion they won't actually accept hand written work), so throughout my university career, the writer's bump would reappear whenever I sat an exam and that was it.

Mine's not on the middle finger, though. (Middle's the longest one, right?) It's on the ring finger. Probably because I hold my pen weirdly, with the first two fingers and thumb on the pen, and the ring and little fingers tucked away.

Although mine's more to do with drawing these days, since I do most of my composing on my laptop. (At first I swore I was going to keep writing first drafts by hand, but you know how it is.) The callus used to be truly monstrous, but it's not so big now. I miss it when I get to coloring, I can tell you. {= P
