Comcast is always terrible for me. (Recent got a fiber company into our neighborhood and couldn't drop them fast enough) Waiting for like 45 minutes, getting somebody who can't do anything, often having the call dropped. It's not technically the fault of the employees, although they chose to work as such a terrible company, but they're just given like 1% of an ability to do anything to help anyone.
I mean, it's the low hanging fruit content. It gets done engagement, some amount of almost nostalgia, but doesn't require much work to post. It's not the end of the world, it just comes in larger volumes and takes up quite a bit of "all". Honestly blocking some of those communities would probably work well to clean up your all feed if you wanted.
There a few things that we just haven't crossed the threshold for yet that I found engaging (if not "addictive") at Reddit, several of which were live threads about an event (NFL/NBA/Soccer/F1/etc). We're not big enough here for that yet, where Mastodon is (you can get awesome interaction on hashtags about topics while they're happening).
The other thing was when a post got popular you could scroll through hundreds of comments with at least some thought behind them, and here it's more like 10-25. The content is often better here, there is just less of it.
Which is fine for me, it's just a slightly different experience than I was having at Reddit, but I think some of those things will come with time.
