When I first started blogging, I used a quite esoteric product (for which I developed a great fondness) called Radio Userland. I can't remember why I stopped using it, but at the time I found myself jotting down lots of short-form thoughts. My style of writing was very different to the longer pieces I do nowadays, and in part I put this down to the lurking "Title" field that TypePad includes: it suggests a formality to individual posts.
But I quite miss being able to throw out any old idea. The conciseness of Twitter makes it great fun, but it's an awkward place to carry out conversations and sometimes I want a little more than 140 characters… so I'm going to start putting shorter-form stuff over on my Google+ stream. I'm also cross-posting longer stuff there, to see how that works too.
