I like what Andy Ihnatko wrote in his post “Life On MarsEdit” about his conception of the perfect blogging interface.
What I really want is a system-wide hotkey. No matter where I am or what I’m doing, tapping it causes a little note card window to pop up. I type a few sentences, maybe click a Twitter-style icon button to drop in a photo or paste in a link (which the app automatically grabs from the frontmost browser window), click the “Post” button, and then I’m back to what I was doing before I had this brilliant idea for a quick post.
Blogging as easy as tweeting. That makes perfect sense.
