Where do you envision this branding being used?
Many things could make the team look like a joke if not done well. There’s no reason that we couldn’t have something that looks good but also tweaks a fun reference that other people will enjoy.
You really shouldn’t have put words to him before talking to everyone else. It’s one thing to ask him if he’ll do it, but it’s another to start him off with your version of what you think it should look like.
However, that will mostly affect him, if he comes back with a design that is heavily influenced by your opinion, and we don’t like it, he’ll have to do another (or tell us he stands by the one he did and we’ll have to find another designer).
But back to the first question. Where exactly do we expect this logo to end up, besides on swag for us? We’re not much of a product. We have our websites and blogs that are pretty much internal to the Mozilla Community.
