I may be the only one interested in this but her eit is anyway 
 
 Following on the question of how to attract new photographers, I did a small experiment by posting the same material on different sites to assess their audience potential. I posted an intro to my post Migrant, traces ( 
https://nikongear.net/revival/index.php?topic=11136.0) on Instagram, X, Bluesky and LinkedIn. 
My followers are vastly different on these platforms 
-   3576 on LinkedIn, from my previous work, unrelated to photography
-   802 on X with my former professional persona, 
-   79 on X on a recent photooriented account 
-   202 on Instagram
-   41 on Bluesky

In short: LinkedIn and Bluesky have the best impact. X (Twitter), despite reposts by other photographers to almost 21000 followers, had the same impact as Bluesky with 12 less followers. It seems to confirm that X is downrating posts with links. Instagram delivered a better coverage of my followers but generated little interaction.
