I wonder if there's a strict template companies should follow or Google and Yahoo are completely unimaginative.
Update: Jeremy Zawodny, from Yahoo, says there's no template and Google copied Yahoo's page. Google changed the page and Matt Cutts wrote a short post about Yahoo copying Google.
I can’t say why someone at Google would decide to do that, but to the Yahoo! UI designer whose page was copied: my apologies. In my personal opinion, it sucks when someone else copies a page layout without attribution.Worth Reading: Comment by Matt Cutt on Jeremy Zawodny's blog.
