I've just sent the following message to Jan Beyer, LEGO community manager, to inform him of the existence of bricks.se, now that it's moved to public beta.
My reasoning if twofold: one, make some publicity for the site, possibly reaching out to fellow experts; and two, make sure everything is OK from a legal point of view. Better knowing about issues sooner than later.
(snipped gossip not related to bricks.se)
There's a new site on LEGO which uses the question and answer format pioneered by Stack Overflow, a programming Q&A site. So far, there have been quite a few interesting questions, including the one with the minifig head, and things look promising.
The site is https://bricks.stackexchange.com/ and is thus focussed on LEGO questions.
However, I have a feeling that there aren't many experts on board now, and it would be great if we could attract more. Could you pass the link around? Via the ambassadors, we should be able to reach a few more persons. Of course, having actual LEGO employees provide canonical answers would be even better, but I understand that's going to be very though to organise, since they may not always speak freely. Maybe your team can survey the site and see if there are questions which you feel are worthy of an official answer from LEGO, and if so interrogate the right persons internally.
One last thing - could you check that everything is OK from a legal point of view? I think the most important things are covered, but if there's anything which bothers you, it's better that the site admins know it sooner than later.
Thanks a lot for the answer, and I hope to see you on bricks.stackexchange.com !
Edit: here are some preliminary comments from Jan — note that these don't mean that LEGO approves of anything else; as a matter of fact I think they'll probably want to contact SE owners directly as Jan also asked who was running the site, but it's a start:
Regarding the website - it should not be called LEGO Answers - this imply that the LEGO Group answers but perhaps "Answers regarding LEGO bricks".
Also LEGO needs to be written always in capital letters and should never stand alone so LEGO bricks, LEGO Sets ...
