> What are the advantages of sortable UUIDs

I guess for use-cases like Instagram's: "Generated IDs should be sortable by time (so a list of photo IDs, for example, could be sorted without fetching more information about the photos)... If you use a timestamp as the first component of the ID, the IDs remain time-sortable... [but require] more storage space (96 bits or higher) to make reasonable uniqueness guarantees" [0]

cf also Twitter's Snowflake[1] which is [timestamp, worker number, sequence number] to give the same "roughly sortable by time" property.
