I use Weather Underground a lot, and since the Weather Channel bought them, there has been a "News" feed attached to the site. It's not all gloom and doom if the topic stays on weather - I'll occasionally click a video or read an article: they range from "Check out this awesome thundersnow!" to "Here's a climate crisis topic," so it feels like a reasonably full palette if Apple goes this way.
What I'm really going to miss with Dark Sky are two features I don't see in Apple Weather (or, at least, can't find) - the Dark Sky Widget, and the scheduled notifications. In the middle of this transition, everything else so far feels like just re-learning where they put stuff that I knew how to use in Dark Sky.
