Somehow, the UI is really buggy for me so far, and I experience numerous lags. I didn't manage to create a post yet, and sporadically, it seems like my instance is not available, due to some server error pages. Usually, after a reload of the page, it is fine again.
Furthermore, the UI is differently worse, than Reddits. Searching is awful, and I miss a lot of sorting functionality or algorithm for bringing up the comments based on likes and sub-comments.
I hope this will become better now, the Lemmy gets a lot of attention. Sadly, there is no completed iOS app yet. I don't like using the Website. :D
But then, it is nice to have a decentralized version of Reddit. And it seems it has already a few users, I hope Lemmy will grow further. I will stay strong.
Edit: A grouping feature for “merging” communities from different instances is much needed. I get it, it's a different instance and probably the users of the certain communities like to have specific rule variations or just don't like the other participants of the other communities. But at least for browsing content it would be a great feature.
Occasionally, I click on a link of a different instance, where I don't have an account. And it is difficult to get that link directly into your instance, so you could comment on or like/dislike it or whatever you wish to do. I guess a smartphone app would do its part there. Or some kind of switching feature, to get immediately to your instance, at the same place.
