I was a bit surprised how much metadata Apple includes for this shared picture (in some of the XHR responses). Not only your email address (the same that's on your HN profile so I assume that doesn't hurt) but also what seems to be your device's name ("i" followed by a part of your last name) as well as what looks to be a unique ID of your device and your timezone (are you GMT-6?).

Wow, you're not kidding! I've never used it before but was frustrated by how broken my other choices were and didn't realize how bad that could be. (First choice: imgur. No longer supporting upload from mobile without their app and mandatory sign in. Second choice: DropBox. Their extension is broken and it saved it as a PDF. Then it saved it as a PNG explicitly but the app was making it too hard to get the direct link to the image without using their share sheet and specifying an email address to send to.)

(I am indeed GMT -6, for at least some chunk of the year anyway.)
