Unfortunately, the XMPP feature that is what Laconica should have been based on was only relatively recently specified and implementations are still stabilizing, which is a necessary step before we have clients that support it.
I'm speaking specifically of "PubSub", where you can publish your updates and they get sent out only to subscribers.
Note that twitter does not otherwise match a conventional IM message, nor does it match a conventional conference room. It does precisely match the PubSub use case, and I still hope to see something based on that. Laconica isn't wrong to ignore it, per se, but they will end up having to do (or have already done) a lot of very, very redundant specification as a result of ignoring it. (I'd think they'd still have been better off taking an existing XMPP server, fixing the pubsub to do what they want, and building from there.)
