Well, there is reasons for it not being promoted by KDE itself that much. 1) They don't want to run a distro. KDE is distro-agnostic. Maintaining their own distribution would imply that this is the KDE distro, where you want to be to get the best KDE experience. (Hint: It's actually not.) 2) They don't consider it a distro. "Distribution" implies that someone spent some time to put together a collection of software which works reasonably well with one another. So, it would mean that they do integration testing. KDE does not do that with Neon. It's just Ubuntu with KDE smacked on top. The Ubuntu-part is tested, the KDE-part is somewhat tested, but the combination of those happens to function most of the time out of pure luck. 3) Many people looking for Ubuntu with KDE on it are (reasonably) new to Linux. If you're more skilled, you'll probably go for openSUSE or Manjaro. There's of course reasons why you might prefer Ubuntu even as an experienced user, but it is still the case that many noobs look into KDE Neon. And KDE Neon is not for noobs. The Ubuntu-part is stable, but the KDE-part is not, it's bleeding edge software. Often not really tested, so things might potentially explode there. The lack of integration testing adds to that. And then as the grand-grandparent comment hinted, KDE Neon does not come with a whole load of software. It misses lots of software that you'd expect in a full-featured operating system, which is also in particular bad for new Linux users. As for waiting for a version that's going to be based on Ubuntu 18.04, I'm not sure, if that makes so much sense. Presumable, or hopefully, Ubuntu will fix that hot mess themselves with 18.04. The most recent version of KDE is an LTS release, so they'd be hard-pressed to choose wrongly there, and they previously had such an outdated version of Qt, because they used that outdated version in Unity 8, which they've stopped developing, so they should not fuck up there either. So, unless you actually continuously want to see the latest development in KDE, using KDE Neon won't make that much sense anymore after Ubuntu 18.04 is released. Also, Ubuntu 18.04 is released in 2018 in April, hence 18.04, it's <year>.<month>. And they usually release in April and October which is why you usually XX.04 and XX.10, with every second year in April being an LTS, so 18.04 is going to be the version number of the LTS. For smaller fixes, they add a number behind that: e.g. 16.04.5.
