I downloaded, installed, and have been using ecto. But I don't really like the end results. I'm really unhappy with the spacing of the posts that I've edited with it. And there is no option for uploading multiple posts.
I changed several posts, but had to go back and re-publish them all one at a time.
<RANT> I think that part of the problem might be how blogger/blogspot treats linebreaks. As a developer, having to uglify my code to get what I want on the screen pisses me off. I can understand the usefulness of it, and its fine in compose but not in code mode. </RANT>
I've started including technorati tags (with the help of echo) in most of my posts. I've actually gone back and added them to almost, if not, every post on this blog & the Game of the Day.
