The team behind Readability has released Readlists, a new web app that can easily turn a set of articles into an ebook and send it directly to Kindle, iPhone, iPad or over email with just a few simple clicks.
Readlists is meant to be a more permanent solution to gathering together articles and reading materials than a bookmarking service. You can use Readlist to piece together your favourite internet posts and save them in a handy ebook format so they never disappear. One of the coolest features is the ability to send out a public link to your friends and collaborators so they can add sources as well. The books Readlists creates are simple, but it filters out unnecessary content the same way Readability does. On top of viewing your own reading lists, you can also check out other popular lists directly from the main page.
Readlists is a free web app, and you can use the service anonymously or with your Readability account. If you've been wanting to start a more permanent catalogue of your favourite articles, it seems like the easiest way to do it, even if software like Calibre has offered a similar feature for a while.
