It fills me with terror
There is not the content checking you get with Facebook, I don't want to get fired for scrolling the wrong thing.
"Just don't use Twitter at work" is what some people would say, I already do not use Facebook and just keep Twitter on in the background. "Don't follow that woman who likes to post photos of her G-cups", but where's the fun in that?
It is irritating that there is no way to turn it off either. Expecting users to change their behaviour is no way to run a system, just look at the Myki ticketing system in Melbourne.
