Not having a limit does not mean you can't post real time updates. But having the limit means you sometimes can't post even a single coherent sentence.
How so? This isn't something where you'll have to decide in a split-second wether to take to the streets in response to this or that development. You could argue that there is some value for stock traders (and tbh, given the result, even for them it's basically the same as it was before), but that's about it.
It's just the "breaking news" frenzy applied to social media. Nothing to celebrate, imho.
Sorry but this was an example of how a real time feed on twitter can be informative in a way that a long form piece could not. A summary of the trial would not be the same as the minutiae that she was able to convey. It was done really well. If all you get is long form from New Yorker or Le Monde, you're missing out.
