It's a good article, as far as it goes. But it could have said so much more about useful responses. Vague references to "encryption services" and "enhanced protections" aren't very useful. Farhad Manjoo's piece, cited therein, is far more useful. I like the idea of an "erasable Internet", although that didn't work out so well with Snapchat. But the major lesson is to think before we share. It's excellent advice to sanitize conversations on insecure channels.
Yes I agree. The focus of article are dangers that using internet can bring and much less possible remediations. At beginning and at the end "Delete" is presented as final solution.
