I realize I'm way late to the party, but I've just signed up earlier today and I've only now been able to browse lemmy (again).

I think it's great. While there are other reddit alternatives, I think I'm sticking with the decentralized stuff moving forward. I've always hated being powerless at the whims of corporate greed. The Fediverse may not be much, but it's a step in the direction I've always supported.
I've also read the recent AMA of the devs, and I have to say I agree with a lot of their answers.
With that said, there are still lots of growing pains. My home instance, for example, was recently caught by a bug wherein our posts and comments wouldn't federate (iirc it was a time stamp thing). It's nothing major as the owner was able to immediately fix it, but that's one of the things I'm looking forward to be improved on.

I wanted to have an instance - a 2nd home, if you will - that's closer to me geographically. I realize lemmy will still have issues like I've mentioned earlier, so it seemed prudent to have 2 home instances. I don't really like the larger ones since I do believe spreading out is the way to go, so I found lemdit.
I hope it's okay that I'm not in your country, though...
Still, I like what I'm seeing so far. I just saw the post about lemmyworld vs hexbear, and I 101% agree with the comments there. I don't want to get political, but I agree echo chambers aren't really that helpful and we should have open minds about things (provided they're legal, of course). Also read the instance rules/description lemdit ethos and I can say I'm more than okay with it. It seems femdit is also pretty stable (there was a hiccup that I saw but it's reasonable), so I think I'll be staying if you guys will have me. :)
