Yes, i remember there have been early experiments leveraging the matrix protocol for many scenarios including blog platforms and social media...But i don;t think its popular to do so. Most people interested in federated social media tend to use ActivityPub (protocol), and use servers and clients already optimized for such a social media use case on the Fediverse (mastodon is a recent popular software stack, but there are many, many others).
