To the long list of evidence of a renaissance of long-form reading because of the Web, we can now add the Longform.org iPad app.

The Web site, which picks out wordy magazine and online articles for readers, started selling an app on Wednesday that pieces together articles from dozens of sources for offline reading on the iPad, effectively remixing all of the sources into a new, text-savvy product.

Great new app by the Longform guys. They auto-stock and auto-curate longer form articles from various publications for you to read on your iPad (optionally using Readability to remove the clutter).

I’m a big fan of services like Instapaper and Read It Later, but I recognize that plenty of people don’t want to take the time to go out and find their own content to read later (though those services have their own way of surfacing curated content as well). This is a nice alternative that fulfills Longform’s mission of surfacing comprehensive journalism. And, of course, it works with Instapaper and Read It Later too.

The iPad app has become my go-to app for discovering articles I want to read. Even better: while I discover a lot of articles about tech via Twitter and RSS, Longform allows me to read great pieces of non-fiction out of my “geek comfort zone”...More than an anonymous web service, Longform is a group of human editors whom I trust to bring me content I wouldn’t discover otherwise.

You look at Longform, which I think is spectacular, and you go 'This is so fucking beautiful.'

I’ve been trying to come up with a good way to describe the newly released Longform app for iPad. It’s a digital magazine on steroids. It’s an infinite magazine, a magazine multiplex. It’s a portable reading room where new issues arrive daily. It’s an evolving anthology of nonfiction journalism.

The point is, it’s awesome. If you have an iPad and you prefer longer, more substantial articles over 350-word pieces, you’ll love it.
