Just an observation from yesterday's search and internet usage - Google has turned its text bigger than before. Now, the text that we type in the Google search box will be larger than what it used to be earlier. So people like me who have been thinking that this is a temporary gliche of the system that may have happened due to some change in settings are wrong and should now get into the habit of seeing a larger text.
IMO, I dont see any reason to enlarge the text when your logo is still the same size. It looks a little out of order but may be google is just experimenting. Lately there have been a lot of experiments in Google. Whatever happened to Google caffeine.
