Nothing revolutionary, just some little changes:
do YOU get the new top bar?
I have had that for... awhile at least, not sure when it started appearing.
Let's call it the navigation bar (aka navbar, from 2007 googlesystem.blogspot.com/2007 ...). They've run experiments for few months with this design:
2010-09-02 googlesystem.blogspot.com/2010 ...
2010-11-09 techcrunch.com/2010/11/09/goog ... (with colors, similar to milivella's)
2010-12-07 techcrunch.com/2010/12/07/goog ... (with Google +1/Me)
TOMHTML: Don't know if the question was for me, but it was a incognito session, so I haven't the new experimental bar anymore.
Jérôme: Thanks for the info. I know that I should have checked the some sites (well, at least Google Operating System...) before posting!
