No. I made my own instance, then I wrote a bot to subscribe to all the communities in all the approved instances. It got to 3500 before I got an error. But now I can find lots of communities easily!!
I had one in .world until it got buggy and then I moved to sh.itjust.works and don’t plan to move again unless something similar happens. I hadn’t sunk much into the other account anyway so it was no big deal
I have two accounts so far. I wish there more of a way to sync them together. Primarily because I sometimes get links for other instances, and can't interact with them because I'm not "logged in" for that instance.
I only have two, though, because my friend created a server, that I joined, and I created a server.
I use this Kbin account as my "primary", but I also keep an account on LemmyWorld, which I use mostly as my login for Jerboa and other mobile apps, since there aren't any Kbin apps released just yet.
