Look beyond your first impression. Don't worry about the so called douche-bags.
I am a light VIM user, but I do a lot of scripting on Windows for work. I spend a great deal of time working in consoles for wsf and ps1 files. Having an editor I can use "inline" with my workflow is priceless. I'm not a power user, my vimrc is all of 8 lines, but I can get in make an edit and get back out without losing step. Plus having one editor on all platforms means the things I _do_ manage to learn at work can also be used at home (on Fedora).
TL;DR
Don't worry about a programs perceived user base. Measure it by what it can do for you.
I think we're forgetting that Hacker News is attracting an increasingly broad audience. How many random strangers would you have to ask before finding one who knows what vim is? How many computer science majors? It's easy to forget that "Unix-based hackers" is a very small minority, even among a somewhat technical audience.
