Probably the next generation's text book...

"Facebook just bought Instagram" Like? or Dislike?

I went to London today and found this at one of my favourite shops, Urban Outfitter
I actually kept laughing.  It's just so funny.
It's explaining what happened in history in the facebook context.
So, for example "Obama was elected" - Equality likes it

It's just like this...

It's very clear and easy to understand as well.
Probably this is the next generation's text book?
