I've honestly been pleasantly surprised so far.

Like, the communities over here are clearly tiny compared to the ones we've been used to over on Reddit, but they're also large enough that they have enough interesting content to keep you browsing. In some ways, the environment here feels a bit more welcoming right now than a lot of Reddit due to there being a lot of pretty high-quality content from folks that clearly want this place to succeed.

That said, there's still some growing pains. Some of the instances are pretty sluggish, there are bugs that need to be worked out (this isn't to knock on the devs - I'm thankful this works at all!), and the number of niche communities is still vanishingly small.
