One of the issues I deal with when it comes to consistent blogging is that I find myself strapped for time. I am more mobile than anything these days and because of that I have a hard time pulling out the laptop and blogging. So recently I've started using blogsy when I'm mobile and it's working out well. What I like about blogsy is that I can create a brand new post entirely from scratch, just like this one, or I can open up an existing post that's sitting as a draft on my Wordpress server. Here is a short video that shows what it looks like. I came across this by watching an iPad today video with Leo Laporte and have no ties to blogsy.
This may not fit everyone's workflow, but it's working well with mine.
