Calling Publisha a blogging service really doesn't do it justice. Sure, there's a simple WYSIWYG editor that you can use to create articles, but the idea is that you'll these to create "issues", custom digital magazines.

You can publish these at publisha.com, on your own domain, via iPhone and iPad apps, or view them on the Kindle and other e-readers; a Facebook app adds a searchable archive of articles to your Facebook page; and if your content is really good then you can even make money from your work with the built-in ad platform.
