I agree, we should get some designs by professionals as well (Maybe we have already? You never know who is in this community..). I'm just saying this is the one I instantly fell in love with, and I think the D, backwards C with a dash in it, is genius :grin:From this point of view I agree with you...
I like logo on your avatar, it is beautiful and stylish, but... ambiguous - so needs text spelling-explanation next to it (otherwise can be considered as ASH).
is not so beautiful and stylish but easy to read for everybody without additional text next to it - I think it is important and useful thing... And also have a positive smile inside!
Why limit us with amateur designers - I think we should invite professionals for logo - to collect all possible ideas and creativity - so could choose really the best one.
