It might be conceivable on smaller subreddits, but on the big ones it would basically just drown everything into a sea of low-quality threads. I got the feeling that the vast majority of threads never ever make it to the "front page" of their subreddit.
Well, Robert A. Heinlein took the problem by the other end in Starship Troopers, military service is not mandatory, but required to be able to vote. So the only people that might be capable to rebel are eventually the only ones that won't.
I can't tell if your post is sarcastic or not. If you cannot prevent terrorist acts on your soil, the solution is pretty obvious then, it's not to give weapons to everybody or to hire 20% of your population as cop, it's just to be sure that you're not giving reasons to anybody to come and bomb you.
That's the only realistic & cost-efficient approach given the threat model.
You don't need anything beside regular tmux for that, since if your computer crashes but not the remote host, and if you were using tmux on the remote host, the tmux session will still be open, just ssh again and "tmux -a" and you'll jump back into the tmux session exactly where you left it.
That would restrict it to locksmith basically (professional or hobbyist), as opposed to anyone that can find out how to run a 3D printer. Being a locksmith isn't scalable, using a 3D printer is.
Well AFAIK, each lock is unique, and while it's easy to pick each individual lock, it's harder to guess or derive from a few of those locks the master key that'll actually open them all.
> If you think about it, the only thing that RSS/Atom was ever missing from becoming what Facebook/Twitter are today is a central aggregation point in the cloud. A smart startup [...] could potentially spell the death of proprietary timelines.
I've got the feeling you underestimate how important this central aggregation point actually is. Imho I'd even say it's the paramount reason Facebook/Twitter are still the top dogs, people are just attracted to the (unique) aggregator which already has the most people.
