This is always a spectrum from how long it was since the last Debian stable release. So about 2 years max.

Modern release cadences make it crazy anywhere but Debian, but security patches are very timely. If you’re dealing with newer features, driver support or java/npm packages you’re probably also outside the typical defaults, but there’s generally some people working to keep the common ones up to date.

Still not my preferred way to handle updates and in some cases… kind of abusive to the maintainers who constantly haVE to deal with bug reports from “out of date” Debian users. The xscreensaver maintainer has some choice words. But it works, has for years with no sign of slowing.

I mean it predates a lot of the pervy anime, but Usenet looked the same at the start with lots of Unix/computer boards and an alt.

Computer enthusiasts gonna enthusiastically talk about computers. People who pick up and move to a new platform are likely to be united around being technically competent enough to get there first, and everything else second.
