Yet another reason why jargon sucks

Yes, it's useful for communicating within your group, but as soon as you step outside that circle jargon becomes a problem. That's true even for scientists trying to communicate between disciplines and sub-disciplines of a field. At Ars Technica, John Timmer talks about jargon acronyms that look the same, but mean totally different things depending on what science you do. One of his examples: CTL. If you study flies, this can refer to a specific gene. For people who work with mice, it's a reference to curly tails. For immunologists, it's a type of white blood cell — cytotoxic T lymphocyte.
