Expert in the Field

So I was having a debate about web browsers with some CS students here at CMU (yeah, we're nerds). And at some point someone was disagreeing with me, and someone else jumped in and said something like, "[Chris] is an IS major; he probably knows what he's talking about." (because IS majors do a lot of web development).
Now I know I'm not an expert quite yet, but sometimes it's nice to win an argument just on the merit of my experience.
