hmm. I think i could help with that. @mix
Length will be an interesting factor. They have to be useful, but also very short. Will ponder and see what I can come up with.
Some select photos (maybe presented as a slide show) should do it, especially if you can select some photos from all over the world (like Windows 10 lock screen style). - @Gergely Polonkai 💻
While I love the idea of images it's a bit tricky in this situation. The problem being that the user is downloading the 'verse while you want to show them these images. Assuming we want to avoid a centralized solution, how do you indicate which images from verse should be downloaded, for display here? You could use tags (or something similar), but that's EASY to abuse. Pretty soon some jerk will tag some porn with it and now we've got a terrible onboarding experience.
'whatever image has most recently been loaded into the db'? - @Richard D. Bartlett
again, too easy to poison, or simply be a lame onboarding experience. Lots of the images people post here are just not .... "ooh look at this interesting thing you're starting" quality.
Maybe Mix creates a new identity for "onboarding images" all that identity does is post images to be shown during this stage. Then it's a carefully controlled set where we don't have to worry about copyright violations or porn or other inappropriate stuff. The client could ignore downloading blobs (to avoid slowing down the initial setup) until after the main indexing is done EXCEPT for images from that feed which it would start downloading immediately.
