A particularly popular post by @astrodicticum provides an opportunity to compare interaction numbers between Fediverse and Bluesky specifically for the German-speaking astronomy community, on the occasion of #ag2026garching this week:
https://chaos.social/@astrodicticum/117241440779404836 and https://bsky.app/profile/astrodicticum.bsky.social/post/3mv3oxzfekk2f
At the time of the screenshots, the Mastodon post had 31 replies, 50 boosts, 213 likes, and the Bluesky post had 11 replies, 8 reposts, and 103 likes.
Follow numbers for Florian are 7.8K on Fedi and 6.4K on Bluesky.
My feeling (from occasionally monitoring other post pairs) is that the above interaction numbers are fairly representative, with engagement on Fedi being approximately double that on Bluesky.
Well, anyway. Congratulations to Florian via all available channels! 🎉
Man hat mich mit dem Bruno-H. Bürgel-Preis für die Popularisierung der Astronomie ausgezeichnet 🥳 War ein schöner Tag bei der Tagung der Astronomischen Gesellschaft in Garching. #ag2026 #ag2026garching
Quick follow-up with the numbers from LinkedIn:
A LinkedIn screenshot from earlier today shows 16 replies, 1 repost, and 172 likes.
Follow numbers for Florian are "500+" on LinkedIn.
This places the LinkedIn reactions somewhere between Bluesky and Mastodon.
