I don't downvote on request (for reasons I have occasionally expressed I consider that self control strategy to be poor).
Go edit C:\Windows\System32\drivers\etc\hosts or /etc/hosts to point lesswrong to 127.0.0.1. Works for me. In fact, whenever I get the slightest impulse to go look at lesswrong I deliberately and actively type in lesswrong.com, anticipating somewhat eagerly the Server Not Found message and giving myself a mental reward. This was amazingly effective in achieving extinction) in an excessively reinforced behavioral pattern.
This is useful advice. Thank you.
