This one is a native /kbin magazine, the other one you linked is a Lemmy instance community. While the two sites work together through the Activity Pub protocol, there are some significant differences for the end user and that part of the beauty of the Fediverse, that there is choice. And the best part is that you can subscribe to both on either front end and see everything posted in the environment you enjoy most.

I just moved away from my 7T onto a Pixel 7. I love my 7T. It was definitely my favorite phone. But it seems like things have changed lately and the newer OnePlus phones aren't what they used to be. I still use my 7T as a game and media player for when I'm chilling in bed.
