Lots of drama here.

>I would like to know how this is different from jabber/xmpp and how likely it is that these differences are worthwhile.

I thought the question was fairly content free, and something that someone would be able to answer themselves if they had enough knowledge of XMPP to actually care, and 10 minutes to read the announcement blog.

>I wonder if improving the way XMPP works wouldn't ultimately create a better result. After all, a lot of thought and experience has by now gone into it.

A vague objection and a truism. Sorry if you felt bullied or something.
