one other thing could be the group feature on BSN, I think there even is a really old one about MEC, maybe dust that one off and run with it. That could also bring back the Diaries, which otherwise couldn't be continued with facebook or tumblr.
I can't stress it enough, but with the demo we had the odd situation that we needed to show it so early to get feedback and see if what we're doing is what people would be interested in and if they have suggestions for improvements versus the demo being too early.
My personal opinion about it is still to keep things quiet for a while until we have something really, REALLY big to show and then go full force with getting the word out. Until then I'd prefer to keep things to regular, small updates for those who want to follow the process, but not make a big deal about it. Just make sure the people who already know about MEC and are interested can see that we still work on it - no matter the size of the team or how slow the progress seems to be - and it hasn't died and rots in a corner without anyone noticing ...
can you tell that I shouldn't do promotion? XD
@Mesina
did you have to mention the EC?
I don't even know the feeling I'm having towards it, some odd mix of excitement and fear ... it could be a real way to fix the ending, on the other hand it could make things even worse AND cost me the remnants of faith I have in BioWare ... which is really a shame, because Me3 ending aside, I don't have any major complaints (yes, I liked DA2

)
