I'm surprised at home many times I actually RTFM and are amazed by functionality that I didn't think was there. It's tempting once I get the core of a language or technology under control (especially when in a rush to deliver a working application) to cut some corners and just lookup exactly what I need (and miss out on all the things I didn't know I needed).
