I would imagine that with something like TextMate you'd soon reach a point where you pretty much know all the shortcuts. With Vim, it seems like this saturation point never happens, even if you use Vim proficiently for years there is still more you could learn and incorporate into muscle memory for better results. It even surpasses the "collection of shortcuts" that many editors are and becomes almost a programming language for text editing. It's uncanny how Vim posts like this inevitably reveal commands and methods I'd never known before, and I thought I was a Vim expert.
