Not my style. Writing for me is not such a 'cold' process. I need to feel the temp and the atmosphere I use word processors for writing articles not forum posts, it just doesn't work for me. Additionally I use a lot of formatting features, I mean a LOT.
As of what is naive I think implementing a feature in the most trivial and lazy way is naive. Once you are ready to allocate 100 post space for drafting you need to define and implement it better than what is done here:
"Push either preview or post buttons and I'll push some garbage on the pile of other garbages for you and it is called drafting in my dictionary"
Lame!
Well it may or may not be your style but your style has quite clearly cost you in this instance so I think you should look at adapting your stance. Some people like to live recklessly and sometimes they pay the ultimate price for that behaviour (or lack of precaution). The draft feature is there just as a temporary courtesy and not an indefinite archive. It didn't even use to exist a while ago until theymos implemented it, but was added as a helpful feature so we have at least some sort of back up when drafting or submitting a post (sometimes posts didn't go through and we lost them completely before), but it really shouldn't be relied upon as an extensive history of every draft you might make, and again, you really should have back ups if it's important. If you must write the thing on here then save it in a word processor after just in case, but if that's still just not your style then you may run into these issues again. Hope for the best, prepare for the worst.
