Once I actually buckled down and started learning how to use it, I was surprised by how quickly and easily a natural feeling of "this is how it should be" developed while using Vimperator. Of course, there's a lot of positive transference of knowledge from my heavy use of Vim itself, but still -- I didn't expect to find it this easy.
I think part of the reason may be that every single keyboard-driven browser I have ever used before (Lynx, W3m, Links, et cetera, ad infinitum) was so awful as a Web interface that I became convinced Web browsers were a uniquely GUI-suited type of application. Vimperator is definitely changing my mind.
Thank goodness.
