Mmmm. I've read all the above posts, thanks all for comments...
but i am not convinvced that the research is 100% correct...and perhaps the research is now stale itself or has changed. has an update to that research been considered/done?
and where is the risk factor?
if i hadn't wanted to take some risk, there wouldn't be many of my maps and themes out there to play, or others' wouldn't be making their sort of "out of the box" maps that gives CC some variety.
i notice the logo can change for the addition of some "olympic" type CC theme, and there are the seasonal events that go up in the top right corner banner...
so why not change the maps occassionally also?
Agree with those who say this is not totally a biggie, but any change can be change towards a catalyst for bigger improvements, no matter how small.
