BlueSky has for some reason far more biologists than Mastodon:
Searching for 'PAG31', a currently ongoing large plant and animal genomics conference, reveals about 20 different posters on BlueSky with about 60 posts and only two posters on Mastodon with four posts (one's a company). Twitter/X still has more posts than BlueSky, though. Scientists are creatures of habit.
That’s probably because many people have not enabled search indexing on their Mastodon accounts. If instead you search for the #PAG31 hashtag you’ll find nine different posters (still too few, but more than two).
