Nextcloud asked in a poll at https://mastodon.social/@nextcloud@mastodon.xyz/115095096413238457 what database its users are running. Interestingly one fifth replied they don't know. Should people know better where their data is stored, or is it a good thing everything is running so smoothly people don't need to know what their software stack is built upon?
It's funny that the headline frames it as "a big number" when in reality majority of users don't know what database they're using and probably don't even know what a database is. Such polls aren't useless but you always get skewed results towards the more technical population. They would have to create a poll inside the nextcloud webapp to get more balanced results.
