Was it only a decade ago that a blackberry was a mere summer fruit? That green was just a colour, and reality TV was that one show sandwiched between music videos on MTV?
There were, of course, huge political and social upheavals that roiled our world in the past decade.

TWITTER: The new social network introduced tweets, retweets, follows and trending
