I really don't understand Google products sometimes. Google+ Photos is different from Google Photos? Google Docs, Google Drive, and Google Sheets[0] are all separate things, though somehow interconnected? And I'm a technical user. I literally don't understand how (or if) non-technical users are expected to be able to understand how these work. But seriously, this has to take the cake. "Google Photos" is replacing "Google+ Photos", though "Google+" is still around, and you can use Google+ to share photos from "Google Photos" (but not "Google+ Photos", at least not anymore). [0] Going to drive.google.com and then clicking "New Sheet" will redirect me to docs.google.com, even though Google Sheets was (at least at one point) presented as a "new" product distinct from Google Docs. At least that's how it seemed to me when they launched it.
