a) I'm also not a big fan of the 'animal-theme'
b) I do believe this should be discussed openly, yes it takes more time, yes there is a lot of repetition, but either this is open or closed! As well as there is always someting new in every thread.
If you start having the decisions and discussion going on behind closed doors, rumours start, the project is no longer a 'community effort', which takes away the XOOPSfeeling, the idea of XOOPStopia, where we all work together and contribute according to our skills. Yes there is trolling, but the way we deal with this as a community, is a sign of our maturity. That's why your criticism is appreciated, which doesn't mean that others have to agree.
c) I like the robot man best, as Japan is world leader regarding robotics, and the 'birthplace' of XOOPS. Further it is rather neutral. Also it allows for easy integration into logo.
d) The artwork provided by Herves friend is great, but I'm not convinced, that it would be a suitable concept to addapt for XOOPS. XOOPS has (currently) a toy-like-feeling as it is, and I believe we want to move a little away from this
e) There is a difference between 'logo' and 'mascot'. I believe XOOPS the name is suficient for a logo, and that we don't have to step into the shoes of others, and follow this hype of 'identity via abstract symbol'. You mentioned Germany, don't you feel reminded of other symbols, when the abstract use of geometry takes over? I do!
The addition of a mascot though, should be helpfull for recognition purposes. XOOPS is an effort of XOOPStopia, yes, we unite the young and the old, the incompetent and the professional. You can use XOOPS if you know nothing about web development, or you can use it at a professional level.
We are different, so why follow all the others. I know people will hate me for saying this, but Mambo has one of these non-expressional logos, let's not follow them in that direction!
My 5 cents...
