Now that Internet Jackass day is over, I can share my favourite April foolery. From the April 1, 2004 edition of TidBITS: iChat AV 2.2 Public Beta Adds MSN Support. I read this one in isolation from the rest of their April Fools edition, and it was subtle. I spent a few minutes looking for the beta before deciding it had been withdrawn. It took me months to realize it was all a joke.
