For my part, i don’t consider forums social media. I may be in the minority, but im not as worried about stranger danger or cyber bullying as much as corporate control over content and privacy. i have never used snapchat, but i assume part of their revenue stream involves advertising and selling private data. maybe snapchat is very responsible about these things, but there is no oversight. take facebook, for example: a whistleblower just alleged that facebook targeted teen girls with weight loss and beauty products when it detected that the girls were feeling bad about themselves (say, when they had deleted a bunch of selfies). these exploitative and predatory decisions (to target an individual) are not approved by an ethics board. they are not subject to scrutiny. the only time we become aware of them is when some executive gets laid off and has a sudden crisis of conscience/lucrative book deal. maybe a ban on individualized ads and content feeds for young people would be enough to fix big problems. forums mostly don’t suffer from those problems.
