I always find short variable/function/class names are often developers optimising for themselves right at that point in time, but when you get two years down the line and the developer has disappeared into the sunset you're stuck with it. I think since I started programming professionally I've stuck to expressive names (not necessarily long names), mostly for code self-documentation. It's nice, most editors/IDEs tend to have name completion, even if it's only document bound, so you only need to type it in full once.
