It actually does tell you.
"What does LWN stand for, anyway? LWN, initially, was "Linux Weekly News." That name has been deemphasized over time as we have moved beyond just the weekly coverage, and as we have looked at the free software community as a whole. We have yet to come up with a better meaning for LWN, however."
>The acronym "LWN" originally stood for Linux Weekly News; that name is no longer used because the site no longer covers exclusively Linux-related topics, and it has daily as well as weekly content.
CNN.com doesn't tell you what their acronym means either.
It's spelled out in the footer: "® 2016 Cable News Network."
So what does it mean?
Currently, nothing. But it used to stand for "Linux Weekly News". Of course, that name no longer makes sense since they're far away from producing only weekly news, but they sticked to it, and I think that this is a reason why they don't use their "full name" anymore.

Notice that it's seven printed pages full of questions that somebody familiar with the thing might want to know. But nowhere does it tell you what "LWN" stands for.
If you want people to subscribe to your thing, step one should be to tell us what it is.
