I honestly don't know. I only just found out about BookWyrm from that post on Mastodon. Interestingly, the text of the toot was autoposted into the text box when I put the link into the link box. That text is from Rambling Readers! I don't want to misattribute things.
That said, I think there's a chance. It would probably show up in the "Microblog" portion of the magazine. That is setup to pick up on hashtags in the Fediverse and so if BookWyrm federated made a post that had a particular hashtag, it might show up here.
But in short, I simply am unsure all the intricacies of the fediverse here. I've really only interacted with Mastodon up to this point (and it's gone well)
That's the same sensation I found with leaving Twitter and joining Mastodon. I found that I was more inclined to engage rather than simply read information, and it was more straightforward to curate the information and people I wanted to follow.
