The team already conducted such advertising , they even run Signature campaign for more than 2 months if i am not mistaken and also a wagering competition but i believe than the team is not satisfied in the outcome so maybe they are asking the community in what is attractive to add in their platform aside from putting campaign and events here.
and these moves they are putting now is i believe will attract Bitcointalk users or even those not in bitcointalk but following Bitcoin as well.
Signature campaign is good, it is common and it is loved. I have to say I have been around here for a long time and way before signature campaign was a thing, we still wrote a lot here, that is how bitcointalk became popular, and now it is a lot better for both people like me who already write here (and on reddit and on twitter and on 2 other blogs because I just like it and not make any profit in any other of them lol).
However, what they are doing here is a unique thing. It is basically just a thing that we get to see and have fun with, it is not like any other place, it is basically just something that we could have fun with a bit more. That is why I do respect it a little bit more, still signature is still cool but that is still great.
