I'm sure it has to do with what you're used to looking at. I forget 
which one is which (heck, I was forgetting which was which even when I 
was taking a logic class). However, & for "and" has a precedent in 
natural language. | for "or" is a bit out there, but at least it looks 
significantly different than &, which cannot be said about ^/v.
