I think a big thing is that the front page is not completely changing in order to grab people’s attention every few minutes. Once you’ve seen what is trending you’re set for a little while, and if you don’t want to explore other communities and stuff you can go on to do something else with your day.

That said, the default sorting of front page posts on Lemmy (active?) has received some criticism - you should check out the other options for sorting content if you want it to look more fresh. :)
