Just something that jumped at me from the FAQ:
Do I need to create an account?
Yes. This way we can manage which channels you are subscribed to and allows you to sign in and change your Castify subscription status.
An awkward turn of phrase. Consider replacing "which" with "the" and "allows you to" with "let you". Or rephrase it completely.
It's great to get all this feedback. Answer updated. Thanks.
Today we're announcing a partnership with Castify to bring you Less Wrong content in audio form. Castify gets blog content read by professional readers and delivers it to their subscribers as a podcast so that you can listen to Less Wrong on the go. The founders of Castify are big fans of Less Wrong so they're rolling out their beta with some of our content.
To see how many people will use this, we're having the entire Mysterious Answers to Mysterious Questions core sequence read and recorded. We thought listening to it would be a great way for new readers to get caught up and for others to check out the quality of Castify's work. We will be adding more Less Wrong content based on community feedback, so let us know which content you'd like to see more of in the comments.
