@davidrevoy I'm just now noticing the photos in the background… Google+ and freenode hit close to home (the former because I followed a lot of Android engineers there, the latter because I'm involved in some open source projects who had migrate from freenode to Libera Chat/etc).
Overall, well done! And, sadly, I suspect this museum will continue to grow.
@digitalfox Thanks. Yes, I was also very affected by G+ closing, it was at that time my account with the most connections to contributors and audience of my webcomic (Pepper&Carrot was pretty new at that time). I remember I followed also many pages and accounts I never saw anywhere else after.
Same for Freenode to Libera; but in this case, the migration happened so quickly and Libera team really supported 1:1 features that nothing was lost in the process for me and all went almost smooth.
