What incentivizes people to report every possible detail of their lives on Twitter and Facebook? You know how I confirm if Instagram is indeed down? You go on Twitter, and everyone breaks out the "I go on Twitter to check if Instagram is down" meme. DSL Reports, and various others have come before this idea. People love yapping about things. ESPECIALLY when it's something negative to say.
The real question is if anyone really cares enough to support a niche site like this. The biggest problem is that food poisoning isn't something that happens daily for anyone.
