You know what day is coming up, right? Just to get you up to speed:
Stack Overflow's first April Fool's day came with glitter, cornify buttons, lots of pink, and Comic Sans.
Last year, all user avatars turned into unicorn images, provided by a web service created by some weirdo with too much free time.
So, what about 2011? Well, while we do have some ideas, we'd be stupid not to ask the probably largest accumulation of… special… creativity on the Internet – and that's obviously Meta*!
So, offer your ideas! Of course you won't know until April 1st what actually happens (and we don't promise anything), but be sure that we plan to reward great ideas with a little more than just a Meta rep bounty!
Except that your suggestions should be a) funny (at least in the eyes of most people), b) doable, and c) awesome, there are no restrictions. C'mon get crazy!
