Transport For London Forget Twitter Handle On Social Media Advert

An innocent observation by a London commuter referring to a slight social media #fail by Transport For London has snowballed on Facebook.

Earlier this week Chris Hewitt, news editor for film magazine Empire, noted that TfL's latest poster campaign advertising its presence on Twitter, had left out one vital piece of information.

Following a Facebook share by UK satirical news site The Poke, the tweet has gone viral.

Responses on Facebook to the ill-advised poster range from "Bunch of overpaid idiots!" to "They obviously got lost being caught in the moment for being so rad to put on their twitter handle."

And as one irritated Facebook user points out: "It's especially handy when you're underground but can't actually receive twitter alerts until your entire journey has been messed up."
