Yeah, they are all freewrites. I write as I can and post, generally writing in one sitting and posting immediately as I finish, unless I get interrupted by family or work.
I find that freewriting is more authentic for my style and process. Too much planning gets in the way of flow and edits out fun and emotion.
I think a lot, though it has changed and become far more difficult since the stroke. Flow state is no longer easy to find, but it is very easy to break now.
