I am also of the same kind of nerdiness, but I still feel that in getting something more or less permanently marked on my body, I'd want it to say something to others, and I feel that an image would be more generally accessible. A non-script tattoo I think is more open to personal interpretation. I suppose it depends on what kind of statement you want to make, and if the reasoning behind the tattoos are more personal than anything, then it stands to reason that it doesn't matter if anyone else 'gets it' or not, but I feel that half of the reason for me to get one would be to display it.
