Twitter is 7 years old today and where most of us would still be learning to ride a bike, Twitter has been changing the world since birth.
The little sprog greeted us in March 2006 when founder Jack Dorsey tweeted this little guy
just setting up my twttr

Now, there are 200 million users in the world and 400 million tweets are sent every day. There were just 3 million useres in 2008 but now it only takes a week for the world to send 1 billion tweets.
The most famous tweet ever sent was by Barack Obama (@BarackObama) whose "Four more years" was retweeted 811,000 times, when he was re-elected to teh White House in November.
And in 2010, we had the first ever tweet from space
Hello Twitterverse! We r now LIVE tweeting from the International Space Station -- the 1st live tweet from Space! :) More soon, send your ?s

Twitter is also credited with playing a major part in the Arab Spring - pro-democracy uprisings in the Middle East and North Africa. Activists used social media to send their messages to the world. 
Pro-democracy bodies used Twitter as a way to spread news like this:
Police forces confronted a group of terrorists who attacked them with Molotov cocktails& tried to block Budaiya road near Sanabis #Bahrain

And who doesn't love some accidental coverage of a major news event? Like how this guy broke the news, without knowing, that American troops had infultrated Osama bin Laden's home.
Helicopter hovering above Abbottabad at 1AM (is a rare event).

He tweeted that since the Taliban probably didn't have helicopters, it must have been a "complicated situation" before wishing he had a large swatter to take the helicopter down to stop the noise - he withdrew the statement in a later tweet.
And Twitter got to a plane crash in the Hudson Bay before anyone else when Janis Krums @jkrums saw this
It got over 1,300 retweets.
Who couldn't wish Twitter a Happy Birthday when it graces us with wonderful randoms like James Cameron at the bottom of the ocean.
Just arrived at the ocean's deepest pt. Hitting bottom never felt so good. Can't wait to share what I'm seeing w/ you @deepchallenge
— James Cameron (@JimCameron) March 25, 2012
The Mariana Trench, in the Pacific Ocean, is the deepest spot on earth. Cameron, director of Titanic, was the first person to reach the trench alone - and the first person to tweet from there too would you believe.
And let us never forget the wonder of the # - pronounced hashtag.Born in 2007, this lovely feature has allowed poeple to come together in celebration, despair or incredulity.
#promnight let us stay up late into the night as we witnessed the government say goodbye to promissory notes and hello to government bonds.
Is there a morning-after #promnight pill we can now take?

Wait... is this the Gathering? #promnight

Went to a house party after the main event last night and got sick all over my suit. #promnight

Considering a #promnight themed remix album: all songs have to be made 10 times longer and have to be purchased over 40 years w/ interest

And in an ironic twist of the internet taking over a debate on the internet, #oirscom let us follow the government on their journey into the unkown.
Anyone else think its funny (in a kind of twisted way) that anti-internet rants at #oirscom are streamed live online oireachtas.ie/viewdoc.asp?fn…
— Declan Jordan (@decjordan) March 20, 2013
#oirscom #oirsocm Well that was a mix of hilarious and terrifying. It was like a live link to the 1930s, did they ask about Jetpacks?

Happiest of birthdays to you Twitter, you can blow out your #'s now.
