I have a week of events coming up in Google Calendar each with a different event location. Why can't I see a map of all those event locations alongside the calendar with all the same event details listed? Why can't I associate a Google Calendar event with a specific album or set of photos in Google Photos and see those in the map and calendar as well?
This is why I'm building https://visible.page with my brother. We have all these capabilities of visualizing data on the web, yet no one has actually put them together in a convenient and consumer friendly way to visualize any type of information together in one place.
All these big tech companies seem to just give up on any kind of significant innovation as soon as they reach a certain level of monopoly on their market. Twitter, Spotify, Facebook, Google, etc. I can think of a dozen significant feature experiments they could try that would make my daily life better using those tools yet they don't.
