It's worth correcting a small point the author makes. "This strategy is tolerable for a social network or messaging app (Facebook got away with atrociously buggy apps for years)." But the truth is it wouldn't be tolerable for Facebook to lose photos or posts. The experience can be buggy, sure, but users should and would never tolerate data loss like this. I suspect the only reason Evernote is surviving this is because relatively few people use audio notes and, so far, text notes work fine-ish. I wouldn't expect that to last.
