Ask HN: What are the 30 subtypes of image/video sharing?

Came across an old startup ideas post by PG. In it he mentions photo/video sharing.

"There may ultimately be 30 different subtypes of image/video sharing service, half of which remain to be discovered."

Does anyone have any idea what those are, or how he even got to the number 30?

The number is irrelevant to the larger message which is that image/video sharing isn't necessarily a permanently solved problem.

How many do you have on your list so far?

I'm not sure, I might try doing a rubric later. Obvious uses cases to start with are the contrasts between FB and Snapchat.
