How can you delete a website?
No seriously, how do you keep the browser from hooking you?
I don't have any apps installed and I often fall into a reddit-hn-local_news1-local_news2-it_news1-it_news2 cycle that I start all over when I'm done with it just to check if something new happened in the meantime! Especially on Weekend mornings or when I come home from work, I can sink hours into that cycle and feel increasingly miserable about it, but the sweet endorphin rush of new bits of information can push that away momentarily.
I have tried editing /etc/hosts in the past, but this tends to only shift my cycle to other websites.
