I always find attitudes toward resumes to be interesting. The entire reason we mention technologies on resumes is because we used them, and (assuming we're not completely desperate) we want to use them again. The mere fact that you have done anything in a language gives you a foot up on the person who truly has zero exposure to it. Experience is compounding, and each small step can be worth dramatically more than the last.

I've met too many people who believe that in order to list a technology on your resume, you must be an 'expert' in it, where the meaning of 'expert' varies wildly. These tend to be the same people who think that "evaluating a prospective hire," means, "find any point of weakness and exploit it." It's a weird, insecure defensiveness. A need to prove candidates wrong, rather than gaining an understanding of their skill set and experience.
