"A way to burn time that doesn't feel like a digital sugar rush" - well said, that was definitely one of the main reasons I used it habitually. In my experience, reddit had a fairly unique balance of being able to facilitate both serious and silly content.

Here from a kbin instance. I’d say I’m intrigued by the fediverse so far, don’t find it too onerous to use personally. Time will tell as to whether enough tech-savy Reddit users make the crossover to create the community experiences that would keep me active here.
