Personal $0.02 (I don't know if any of this applies, it's just how I see the situation): these are not mutually exclusive goals. Just because another .. "thing" is set up somewhere does not change the soul of maemo.org. The internet (& ownership base of mobile devices) is a vast one, and the way communities usually develop is by being useful to their target audience. It is certainly true that maemo.org is well suited to the tinker/hacker audience, but that does not necessarily mean it is the best medium to engage with everyone across the spectrum of device users.

I certainly wouldn't stop reading & posting here just because there is "somewhere else" to go, and I expect the same to be true of a lot of different people.
