Twitter I don't think so but I feel like the majority of people visiting Hack News use Github in some way. Remote Repo, Deploying, Open Source tools that are hosted on Github.
Wouldn't that just mean that they're bound to find out that Github is down without needing to see it on the front page of HN?
Good point.
Is slashdot already notified? nostalgia
Did netcraft confirm it?
the might assume that its a problem on their end / on their ISP end.. Clearly enough people think its relevant for it to make its way onto the Homepage via upvotes ;)
