That is the question at a DigitalPoint Forum thread named Google April Fools 2006: Guesses? In that past, we covered a handful of search related April Fools Day pranks. The first one we thought was what is now known as Gmail. Last year we summarized several april fools day jokes, including GoogleGulp, Gmail reaching 2GB no joke, special version of Google April Fools search, and UnderGoos. Do you think this year it is also Gmail related? 3GB of space that turns out not to be a prank? Or maybe the gmail logo is truly replaced by a woman?
The classic Google hoaxes include the mentalplex, pigeon rank, and lunar center.
What will it be this year? Forum discussion at DigitalPoint Forums.
