Lots of reasonable people are used to being able to find timely and accurate information via Twitter (either from accounts belonging to first-hand sources, from accounts belonging to sources the user trusts, or via links to one of those). You may argue that they shouldn't, or no-true-Scotsman the definition of a "reasonable" person, but the simple reality is that Twitter historically earned that expectation from tons of people. It was the example of a platform, social media or otherwise, that, with a little curation, could produce "timely or accurate information about a current event".
It was an exact counter-example to your assertion. Whether it still is, I don't know.
