Not many people would publish long posts from their iPhone, but I bet plenty of us are at least moderating comments while out and about.

But if you think about a different type of blogger, the more personal, short-take blogger, mobile apps make posting to your blog as easy as updating Facebook. Personal example, I run a blog for my family that is little more than pictures of the us and the kids so that distant family and friends can see what we're up to. Two years ago I would take photos on my camera, transfer them to the computer later that night, upload to the blog, and publish them. Now I just snap a quick shot of the kids doing cute stuff on my iPhone and post it straight away.
