Writing a blog post in a text file first can save you a lot of time. At least once I lost a blog post because of a crashing application. Then I copied the text and/or wrote into a text file first. Nowadays it is a little bit easier. There are drafts in Ecency. And theoretically Ecency is also saving what you write in Waves. I heard that now there is a separate application (?) too for the Ecency Waves. I have not tried that so far.
