I first encountered Steve Litt's troubleshooters.com through his vim-outliner project as a new vim user (20 years ago). I never did get much use out of vim-outliner (I've since written my own outliner mode based on vim-quicktask), but I find something fascinating about his writing. I've never read his books (which are mostly self-published self-help books for nerds?) but his DIY ethic and self-aggrandizing voice reminds me of ESR and other nerds whose writing style I admire.
