Want to waste less time on the web? Undop2 to the rescue! (OSX only)
To quote Patrick Collison:
"I’ve never had much luck with the apps that set out to solve this, like Freedom or RescueTime. They feel too heavy-handed. Instead, I want fairly repetitive and annoying prods that make wasting time less fun—the equivalent of small electric shocks, counterbalancing the Dopamine hits."
Every time you visit a bad site[1] your display will be dimmed. Annoying, and probably not good for the display long-term. So don't do it.
Improvement over original Undop: Undop2 will catch you in any browser, not just Safari.
Usage: download, run sudo python undop2.py
