How has it affected me? It hasn't.
The notion of posts isn't really a thing for me any more, I now just have public and private diary-like spaces where each day unfolds as it will. Add on the garden and I have a place for drafting things before they're published if I'm not ready to write them all in one go.
I have also reduced the friction of posting to the journal further by having the page load ready to go in edit mode, all I need to do is start typing even if I have already saved something earlier that day.
This was already the case over at the garden - if I visit an empty page it opens in edit mode just waiting for me to write. This is what online writing should be like.
