User:JustbeBPMF/Preview before post

Why Wikipedia encourages preview before sending out?

I thinking the edit count will be untrue because some user don't preview and post every time he or she want to seeing preformance or "saving", but another user will preview until certainly it was correct, especially, every user have difference habits. some users saves even made a bit of edit, and another users will be post only done all modify.
