I use Microsoft Word for writing anything (apps, posts, etc).  If you happen to click the "close" button, it will ask you, "are you sure?".  Problem solved. :D

If you don't have Microsoft Word, I supposed notepad or wordpad could work.

If I am that worried, Google Docs. It auto saves every couple of minutes and can be accessed from anywhere, so if I am at work I can edit a post I started at home etc.
