maybe tone down the sales-person vibe in the language? A good model for this on mastodon might be the Feditips account.
As said elsewhere, mastodon is in many ways all about the hashtags. You gotta use them to get seen, but, even more importantly here, people already following particular hashtags are probably the target audience here. “#startrek” and the startrek communities or instances, as an example.
Maybe recommending mastodon users follow communities isn’t the best idea given the way it turns into a firehose on mastodon???
