I had a quick look at my followers, how many accounts they are following vs how many accounts follow them and how much they post. Note log scales!

Quite different from the sixty odd followers I had in twitter after ten years. Fun fact, I joined twitter because of a MOOC on Data Visualization.
Scatter bubble plot (log scale on both axis) showing, for each of the ~1.2k followers of the account posting the chart, the count of followers vs the count of following. Number of posts of each account is shown as color map and size (also log scale) of the bubble. Insights ~300 accounts have not posted at all About half of the followers have less than ten posts ~80 accounts have more than 1000 posts 1 account has over 25k posts

Adiós a Sofia Corradi (1934-2025), conocida popularmente como “Mamma Erasmus”.
Profesora de pedagogía, fue ella quien concibió el programa europeo de intercambio de estudiantes en 1987.
Si estás entre los 16 M de personas que se han beneficiado de ello, dedícale un recuerdo.
