So I’m running into the main problem with Cascade, which is also the main strength: it’s not especially dynamic. Adding a randomly selected item? It only selects that item when the page is published. So not on each load. Which is why people do ridiculous things with JS? (I know from doing ridiculous things with JS.)
We’re getting lots of requests to add blog feeds to people’s Cascade pages. Which is all well & good, there’s even a block type to handle it. Then it came to me: will it update the page when there’s a new blog post? You’d think so, but I honestly have no idea. So I’m adding this post to check a test page that has this blog’s feed as a block.
The short answer: no. OTOH, it’s possible to schedule publishing, and the sites that already have blog blocks (!) are already set up this way, mostly for every four hours. It feels wrong somehow, but it works.
