i do not understand snapchat and their business model. they started out as a sexting app that deletes the photos and that is where it remained for a long time. i remember news of how "deleted snapchat photos can be undeleted" tutorials and i tried to investigate for fun but i could not understand the UI back then and the tutorials didnt work so i dropped it. Apparently its pretty big these days in the kids and they have "streaks" as you mention. i hear multiple hundred thousand streaks and other things but to what end? how is snapchat justifying the storage, bandwidth and processing of data? i mean facebook has ads which they earn, same for twitter but what about snapchat? do they have a sustainable revenue stream because no where i heard snapchat had a paid option. reddit was user funded for a long time with daily goals and all that so that was not an issue mostly but what snapchat done to address that. snapchat is all the rage in my city, kids who are now on online classes send snaps because i hear about it. everyone knows how to make that twistface pout or whatever but why? genuinely curious about it
