Poster is a brand-new iPad blogging app for posting to WordPress sites. It works with hosted WordPress.com sites, as well as with self-hosted WordPress sites like Cult of Mac.
It seems like just a few months ago the choices for blogging from the iPad were limited in both quantity and quality, with the best apps (like Blogsy) often heavily flawed, and the worst apps (the then-available WordPress App, for example) being unusable.
Now, we have an embarrassment of options. And ironically — for WordPress users at least — you can now post images into articles direct from mobile Safari (in iOS 6), meaning you mightn't even need an app after all..
