Firstly, let us say that the photo above is something of a cheat. For Barack Obama didn't send his first tweet from @POTUS via a laptop on a lectern. He did it in the time-honoured fashion - perching casually on his desk in the Oval Office:
Yes, President Obama has a brand new Twitter account.
Hello, Twitter! It's Barack. Really! Six years in, they're finally giving me my own account.— President Obama (@POTUS) May 18, 2015
And after we'd all had a good giggle at his exchange with Bill Clinton...
...it was time to have a giggle at other Twitter users' reactions to this momentous event. Which was, indeed, momentous:
Obama is on Twitter?! I haven't been this excited since the Krankies joined Tinder.— Chuck Thomas (@chuckthomasuk) May 19, 2015
Hail to the tweet #POTUS— Robin Flavell (@RobinFlavell) May 18, 2015
Tweeters' responses included advice for the President:
.@POTUS Dear Mr. President. There are too many states nowadays. Please eliminate three.
P.S. I am not a crackpot— Sheldon Walsh (@sheldonwalsh) May 19, 2015
Calm down Mr President pic.twitter.com/u8PIhCUu9x— TechnicallyRon (@TechnicallyRon) May 18, 2015
Advice for fellow tweeters:
So now everyone on Twitter can barrack Obama.— Andy Gilderdale (@AndyGilder) May 19, 2015
Let’s all follow @POTUS and then say he’s outraged Twitter etiquette but not say how, and unfollow him.— paul bassett davies (@thewritertype) May 18, 2015
Obama a lot less active on Ello since he joined twitter.— Moose Allain (@MooseAllain) May 19, 2015
Not sure he's quite got the hang of it... RT @POTUS Ed Balls— Andrea Mann (@AndreaMann) May 19, 2015
just followed and then muted @potus in what scientists are calling the most bizarrely ineffective passive aggressive protest of all time— Keri (@kerihw) May 19, 2015
.@POTUS Did you know the guy who plays Immortan Joe in FURY ROAD also played The Toecutter in MAD MAX? It's the same guy!— Patton Oswalt (@pattonoswalt) May 18, 2015
So wait, @BarackObama wasn't Obama? Can't believe he'd use some kind of drone to do his dirty work.— Keri (@kerihw) May 18, 2015
And some contemplation on how Joe Biden might be feeling:
Barack has his own Twitter, does he? At last, the final betrayal. pic.twitter.com/sL81NcqWxs— Rick Wilson (@TheRickWilson) May 19, 2015
Poor Joe Biden...
After 6 years, Barack Obama has finally been trained to use Twitter. That means we should expect Joe Biden some time around 2024.— Politics and Humor (@PoliticalLaughs) May 19, 2015
And that wasn't all. The official White House photo of the official moment of the official first tweet also prompted some marvellous picture captions from our Twitter followers:
@HuffPostUKCom 'Exact moment of US economic decline captured on camera'— Oonagh (@Okeating) May 19, 2015
@HuffPostUKCom "Dear David Cameron, please stop begging for a Twitter follow back, it's embarrassing!"— Ian Power (@IHPower) May 19, 2015
Including the favourite Twitter running joke that is Cheggers:
@HuffPostUKCom "One day on Twitter and I've already been blocked by Chegwin"— Twitflup (@Twitflup) May 19, 2015
And, not forgetting:
"Right, how do I mute Piers Morgan?" pic.twitter.com/YyxmGe00ju— SimonNRicketts (@SimonNRicketts) May 18, 2015
Marvellous. Welcome to the wonderful world of Twitter, @POTUS!
