Thinking out loud about blogging from this space.
It's pretty close to being able to do what I do in Electric Drummer in an outline, just need a few more options, they would fit in the context menu on each post as you edit. Lots of room there.
The blog rendering would run off the RSS feed. I probably would write something new and very simple, almost like an RSS feed browser.
The reason I would start with a pilot project here is because there are other people here, already. And if I said something provocative that you knew other people would see, would you be drawn to that? I trust the people I've invited here not to be spammers.
We might be ready for that. We put a lot of effort into the comment system here. We plan to use the new features to create a very new kind of web.
No one tries out new ideas in the blogging world. That could change.
