IMHO, the old monobook is getting old and tired, and it's marginally relevant to Wikimedia Commons. And it's so similar to many of the projects that it's not always easy to tell that you've moved from one wiki to another.
And, judging from offsite conversations, some of you are agreeing with me. But not all of us are good at designing skins. And how do we change it while upsetting the least amount of people?
I propose that we formulate a contest to come up with a new, more exciting monobook.css.
What do you all think?
