Agreed-- I find the "durability factor" very attractive, too. I'm getting a bit tired of having to perform "emergency rescue" missions to retrieve my content when sites suddenly announce they will be shutting down at the end of the month... it's my hope that will never happen with Steemit. And my hope is also that this will not become a Facebook-like pit of baby pictures and people sharing what they ate for breakfast. Maybe that sounds arrogant... but I think there's a place for everything.
