As a new user, I'm enjoying Mastodon's vibe so far but the one thing that is a letdown is the trending hashtags. I've been checking them regularly over the past couple of weeks and it seems like they're pretty much always like this.
Even on days with big news stories, people on Mastodon are only talking about what day of the week it is like company employees on some internal message board?
Is there anything that can be done to liven them up a bit?
You're kinda not wrong, and definitely not wrong about the breaking news part, but I've found a lot of lighthearted goofing about to do on there, partly from following silly bot accounts & boosting them, and partly from the more relaxed & imo better curated all/other server feeds of smaller instances.
On the larger instances it's harder to find this good middle ground, especially if you go in without anyone in mind to follow. The other weird quirk to all this is that by default Mastodon is more private than spaces like Twitter, so people have to actively choose to tag their posts and enable features that might help others find them. Also, if you don't have many remote followers, your posts won't federate to as many other instances, and similarly, if someone limits who can follow them their posts (which may be fun & great) won't travel as far. The latter isn't a default enabled setting or anything, btw, but I think it may have a subtle effect on the general vibes of the space.
