the tab system of google is not clear enough for non experienced users to use (my father tried Google once and gave up, he went back smiling to Yahoo and thought his son was a barbarian who knew nothing about the web π)
I especially like the part they added recently :
News-New!
but TBH I don't use google portal anymore, I installed the googlebar and that's my search engine (I see results pages only now). Great thing about the google bar is that you can access the google cached pages (meaning that if you changed something and google has it in search cache it's still accessible π)
