Ditto @Chiogtr4x post above. The middle pickup on a strat is so underrated. Among other useful tones, it's where you get the jangle from a strat.
Another well-regarded middle pickup player is Doug Martsch of Built to Spill. I believe his primary strat doesn't even have a pickup selector -- it's just permanently set to the middle pickup.
I may be blowing patootie paste here, but I seem to recall that the neck pickup is located at a "node" position on the string vibrations, thus enhancing its tone. The bridge pickup, in its location, senses much more of the fundamentals of the vibrations, rather than overtones, thus contributing to the bright edge of its sound. A pickup in the middle would not have the depth of the neck or the bite of the bridge. Some may like this lack of character, but it leaves me a bit cold. Having owned, in my long and checkered career, several Strat-types, a Gibson ES5, a Nashville Power Tele and an Epiphone P93 Riviera, and none are now in my collection (sure wish I had that ES5 back), I've come to the conclusion I'm not really a middle pickup fan. YMMV
