The only reason we can’t communicate with Kbin is that Kbin is currently under siege with all the new signups and isn’t federating properly. It’s a problem from their side too.

Once they can get stable and federate normally the two will be able to communicate just fine, like we were doing before the sudden influx.

Edit: That said, if you prefer the look and feel of Kbin there’s no reason not to go with that instead. Maybe wait til they sort themselves out though :D
