It’s different. From a software standpoint much more mature since it’s older and doesn’t have to manage the technical depth that comes with the fediverse, since it’s not a part of that.
The culture is also different. Not sure how to describe it but if I had to I would also call it “more mature”. Deeper conversations and the different structure of the sites makes it different. There are also no moderators or freely created “magazines” (for now).
Have a look at it and feel free to message me if you are interested in creating an account.
