It should be mentioned that the author has very strong conflict of interest.

Also, isn't the appeal of vim that it's universal rather than that it's beautifully coded? I don't have the expertise to care about weird indentation in source code personally but I like that the text editor I have on my daily-use machine is probably also accessible on a 80's-era server on the other side of the world...

Vim being universal is pretty meh. Try using vanilla vim, you'd hate it after using non-vanilla for a while. It is like a whole different world.

At that point why not just use sublime or w/e.

I have changed over to neovim for most of my editing, but the one thing I have found is that it seems much slower to start up. Pretty sure this is a bug they'll fix soon, and other than that it's really pretty great. I don't actually use the Terminal window feature, but there are a few things about it that I like: 1)Decent python2 and 3 support (yes both at the same time) 2)Getting the * and + registers to actually work seems less annoying than in regular vim (ymmv at least I don't have to rebuild neovim from source to get these). (check out :he quoteplus and :he quotestar if you don't know - these are awesome)

Author claims that vanilla vim would never support async linters, but that's changed now: https://github.com/w0rp/ale

Would it exist in vim without neovim. The landscape has changed, but part of that is due to neovim's existence.

Also neomake (https://github.com/neomake/neomake) is supported in Vim 7.4+ too, with the async features available from v8+

Have used Neovim exclusively for a few years now and I can’t say I need to switch back. It is Vim now.

how do you integrate neovim clipboard with system one? I use KDE/X11 although I do not think that should be relevant.

I just pipe lines to xsel. Not elegant, but works.
