Receiving crumbs of info as to WHY a service is down is interesting to some. These are also great for tracking postmortems (unless they take awhile, then it's a separate post).
Speculation is entertaining to many as well. Or perhaps this sparks an idea for someone (omg, GH is down ALL THE TIME, time to build a novel competitor!).
And given the crap state status pages are in these days (stop showing green when your site is down!), these are great for knowing when a service is operating again.
