@indw I often start writing in something like iAWriter, then decide once I’m done whether I’m going to put it in DayOne or online. Sometimes the “bigger” version goes into DayOne, and I cut it down a bit to what I am willing to say publicly for my blog.
In the end, while I’m quite conscious that what I publish is public, I put 0 thought into what’s on the timeline versus my website. If it’s on the web, it can be read. People who follow me can do so on various timelines, RSS, or just visiting my website. I don’t control who reads, I just control what I write. And I don’t publish something to be read, but I do publish things that I won’t mind others reading. Everything else is in DayOne.
