What was the point of having the whole logo contest and vote and ratification of the colored logo if you don't stick with the vote results?
Are you going to change the logo every few days? (I suppose that would be in the wiki spirit, but it seems a bit silly.) In that case, just make the logo world-editable and we'll all have a traditional edit war over it.
And who decides when the logo gets changed, since apparently the vote didn't matter? You've even removed the logo-feedback link from the main page, so one has to hunt around on google to find it now.
