Phil in SF@luis_in_brief yes, you can. i have done it. however, i don't think boosting from mastodon helps with exposing posts from one bookwyrm server to another. bookwyrm accounts would need to follow mastodon accounts (not a widespread thing) and mastodon boosts of reviews may not be fully ingestible back into bookwyrm reviews. not certain of the latter issue however.
