What is the next online service or community that you love and have been using intensively for a good while, that will be unceremoniously acquired, discontinued, maimed, or shut down, causing you to lose a good deal of value and pleasure, even if you manage to export data to some useless format?
Mine is #Goodreads possibly 😞
Nice, thank you! I think I didn't know of that one.
I actually registered on three or four #Goodreads alternatives a while ago. Never actually used any of them after that though, since they're always worse than the original, and their communities and book DBs are still tiny in comparison (obviously) 😟
If I do switch at some point, I'll be more cautious this time and look at things like: open formats and protocols, data import and export, free software, who's behind, monetisation model, etc.
