This question already has an answer here:
- What should our elevator pitch be? 18 answers
In addition of the logo question I would raise the same question for a slogan.
Give in one strong sentence the real meaning of our lovely CR community.
One of the things the sentence could contain :
- What we do for you.
- How we work.
- We don't discriminate.
- We vote a lot for good questions and answers.
- We do have the best chatroom.
I don't think a lot of sister sites do have a slogan, but remember CR is unique so we deserve unique things.
