It's not that simple. This is not a 'rebranding' - it's a marriage. The maemo community is going to have to connect to the different needs and expectations of the moblin community. That they don't use a forum is just one element. Moblin seem to be highly developer-oriented, for example, whereas maemo.org is increasingly an enthusiast and user community as well. The Moblin community structure is completely different, too: they don't have an equivalent of the Maemo council. If it were just a rebanding, I doubt there'd be quite so much fuss all round.
