I feel your pain. These things are frustrating. I love @esteemapp, but I have lost posts just because a misplaced finger zapped everything dry. I have to remember to save as draft every so often. But I get in the zone and don't think about it, then--bam! Fat finger.
Throw some holy water on it and drink a fifth of whiskey. You'll feel better in the morning.
Murthy's law, if it can go wrong, it will go wrong...fat fingers always strike when you least expect it. So yes, just...save more.
It had been a few days so it's actually nothing big now, now writing something pretty strange (compared to my usual stuff) and will probably be around here before too long :D
