Sorry, just throwing in my 2ct, not even knowing how to correctly quote 
(I receive the digested list).
Imho the biggest chance, the biggest potential for devuan would be to 
just start off as "another" debian, just without systemd and, and I've 
read about it on this list, with maybe vdev as a replacement for udev.
To discuss nano vs vim as default is pretty much besides the point (as a 
vim user I'd still say nano is a good default because it pretty much 
explains itself in the bottom bar).
I've been trying several Linux/BSD over the last few years and felt 
pretty uncomfortable with not being able to kill some systemd services 
on fedora, so that's where my n00bish scepticism set in. I consider 
myself very much a plain "user" without much understanding, but I feel 
that I'm not the only one who has so far adopted Debian as the most 
common distro and gotten acquainted with it. I also feel many users feel 
uncomfortable with the whole systemd cluster and would eagerly switch to 
an "oldschool" Debian which they got to know how to handle.
Uh, this is just a little "rant", but I really look forward to see 
Devuan released. For the moment I've switched to gentoo, which I fell 
might even suit me more than Debian, now that I've invested some hours 
to grok. Nonetheless I guess I'd go back to a stable systemd-udev-free 
Devuan if there was one.
I'm esepcially excited about the vdev development and kudos to the guy 
who's doing it.
Summary: what I wanna say is that "systemd and udev free Debian" would 
imho be the thing to be really successful so even for the people working 
in their free time there is quite some potential for this distro to 
immediately go popular and successful, if everything else remains 
debian-ish.
