Yeah unfortunately it's not quite ready for mainstream yet. I've noticed over the last several days that I've been using it a bunch of small UI things that would really frustrate someone without a high level of tolerance to such. e.g. you get a notification telling you that you have a message, you click it, but there's no message; so you do a control-F to try to find it... nope, still no message; next you have to hunt through the entire page for every "expansion block" and "Continue thread" (which takes you to another page) and those "auto-collapse" (based on comment threshold), and I disabled "auto-hide" but surely that might really be a problem if there's a Notification for something that becomes impossible to see later without changing your configuration settings.

For extremely basic things it's fine... mostly. Just never edit your messages and someone will be fine. I say that b/c you can't edit comments in-line in the page where they are at, and once you are done editing one, it doesn't take you back to it but rather to the OP thread instead. Whereupon again you have to hunt for your comment all over again as mentioned above. Which is especially annoying when you have to do it multiple times, b/c there is no Preview feature to let you know what is coming after you submit it - did you insert a space between your [alttext] (link here)? did you mess up your "quoting" rules? does an image not render?

(the above on purpose:-)

On the other hand, they can allow YouTube embeds without having to wonder what is on the other side of that sus-looking link and click and leave the page. And personal instance blocks - that actually work - and categories, and like it will tell you, for every comment, both the time something was posted and the time it was last edited, woot!:-) There's just a ton of fantastic features, more so than Lemmy in many ways, and yet at the same time less too - if that makes any sense at all.

But then again, more people know how to code in Python, so I hope it will catch up soon:-). That might even be what we're seeing now - the core UI needs to be not monkeyed around with by a bunch of people all working at cross-purposes, but then all these nice little additions could each be someone's side project? But they need to get the core working too.

That's a highly specific comm though and most instances/comms would not be okay losing the history. You also inevitably stunt growth and lose some users during such a migration. It would be much better if ActivityPub allowed an instance to change its underlying representation, while keeping all the users and post and data but unfortunately this is basically impossible.
