In a global world, plus now some really factually wrong information on the Internet, etc., April's Fools jokes don't have the same impact anymore.
Beside let's remember: April Fool's tends to be "celebrated" by only certain Western cultures. It is cultural in context. People elsewhere simply don't get it unless they are told what Apr. Fool's Day means.
In the places where I've worked, certainly is not tolerated across an organization: ie. never send an April fool's joke to a whole pile of employees that you don't know or don't even bother wasting people's time.
Save it for comedy shows.
