This whole "it's apples to oranges" claim is bullshit. Both Word as well as LaTeX can be used for anything from writing a resume, making a technical paper with a few simple equations, to writing an entire Vector or Linear Algebra textbooks. When you have two options for doing the same task it's very much comparing apples to apples.
Yes, they each were originally built with different objectives and different target markets, but they have since aspired to be usable for all the same things. Of course, they each have their strengths and weaknesses.
But I don't get how do a bunch of folk here feel justified in arguing against someone saying "there's room for improvement" with clear viable suggestions on the details too. I know that hating on MSWord (or MS-anything) is fashionable on HN. But you can't seriously be defending
* the steep learning curve: throw your 14-year-old who's doing a math assignment Word vs your favourite LaTeX editor, see what happens;
* lack of WYSIWYG-like feedback-loops: you have to wait a full minute on decently sized documents to see the result of adding that equation that took you 10 seconds to add;
* syntax holdups: you miss an underscore and your document is broken. All the way through. And can take an hour to fix even if you're skilled. People writing documents that need LaTeX's power aren't always coders, and debugging is not a fun or planned-for activity for anyone.
I also don't for the life of me see why someone has to "be an expert, not just written a couple documents casually in undergrad" to be able to comment on the flaws of a product. They're as much a user as a power user, and obviously the power users went through that stage too. Losing sight of your past difficulties (or being gifted in LaTeX) doesn't make them irrelevant for people not in your current position.
Loosely relevant: I smell hardcore "hacker entitlement" around people using LaTeX and defending it including all its stupid barriers to easy document-creation tooth and nail. Hardcore programmers do this with way too many things (like Linux, and development environments for almost any language). And it's just really frustrating for a lot of people to deal with =/
PS: NeoVim sounds like someone finally got off their high horse (or from whining) and decided to actually make something better. Thanks!
