Re: What's the difference between a trekkie and a trekker?
As others have pointed out, "trekker" was just invented because the term "trekkie" had come to have a negative connotation. Kind of sad that fans didn't just decide to stick with the original term and own it.
QFT, and one of the main reasons I'd rather be called a Trekkie.
