Last year Google sort of announced Gmail on April Fool’s Day, and nobody was sure whether or not it was a joke of some kind. (Turns out it wasn’t, obviously.) This year, they’ve put up a real joke, and they’ve announced that they are doubling everyone’s storage to 2GB. My account actually says I have 1386 GB available right now — 10 times the storage that I’m actually using.
Update: they’ve also created a clever April Fool’s search. (Check out the results for this site.)
