It could become one, depending on why twitter is down or how long it stays down.
But yeah, nothing much to say or show for now.
Twitter being down (widespread) for even a minute seems pretty huge imo.
Right, I would love to read such posts with the forensics on what happened. But just 3-word phrase titled "posts" with zero-content should be discouraged from floating to the HN front-page.. otherwise this would be just another "reddit".
If only because twitter is usually where one turns once an outage is reported on HN.
