moral of allllll these stories. dont use free stuff. because it never lasts. EVER.
you start to depend on something and its gone before you know it.
This "free stuff" has lasted a lot longer and has been a lot more reliable than any of the paid services(Kaphost, Hammerhost, RTB, etc). I'd say almost 3 years is pretty damn good actually, nothing lasts forever dude.
I do agree with you on the fact that people should not depend on it though, but that also applies to the paid services too. I always have a back up option for dedicated hosting and other productive hosts should too.
