I want to be able to write down a short idea, one or two paragraphs, hit Publish (or the equivalent) and move on to the next thing.
When I publish it should...
Appear on my home page.
A link should be sent to Twitter.
The full text should be sent to Facebook or/or WordPress, including a link back to the original post. Revisions to the post flow to Facebook and WordPress.
Be included in my RSS feed, with full text.
The most important thing is it be quick. I lose good ideas because there's no place to put them, or if I put them on Facebook I'd lose them shortly after they scroll off (why is it so hard to find stuff on FB). I need to be able to open my outliner, hit the Big Plus, enter my idea and get back to what I was doing. Quick.
This is essential for my blog and also for my worknotes outline.
