I agree that projects needs more visibility, and I don't think there is any problem with starting from empty forum which is dedicated to Nemo. So far this is all rather confusing even for those involved, imagine some newcomer, who wants to find out about it. Should he/she go to Meego wiki? To Meego forum, or may be to Maemo forum? What about Nemo wiki? Mer wiki? Should all of those be monitored for updates and interesting topics? Should the user first find out what Maemo is? Or may be Meego? The history of it all which led to emerging of Mer and Nemo? While I like history, not everyone has time to delve on all of this really.

Don't judge everyone by your experience, many people never even heard of Maemo or Meego, while they potentially can be interested in Nemo. So for the sake of simplicity and clarity, and for the sake of new users / project participants, I think making a separate site / forum etc. will definitely help even if the user base is very small at the moment.
