good ways of signalling "nerdiness"
I would specify instead: signalling "I care about good communication and avoiding misunderstandings due to poor use of language and syntactical ambiguities/misinterpretations"
I've got this idea from I-don't-know-where that this kind of signaling is a useful, cost-efficient sonar ping that'll publicly filter for certain types of people, notably those who care about grammar and those who care about avoiding ambiguities. I think attracting both of those groups is a suitable compromise when the only obvious alternatives are much costlier.
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.
