Ah the old hosts file blocklist trick. I tried that 20 years ago, but my dopamine craving brain wasn't fooled. Paul Graham tried owning two computers, one without internet https://paulgraham.com/distraction.html . That too didn't work for him. My current strategy is to only use an RSS reader in my browser. HN posts with x upvotes, a few twitter accounts, a few facebook accounts, a few youtube channels, and a few substacks are all I see. No ads, no infinite feed. Every hour or so I can go to the feed trough and consume a few posts. Feels healthier. The distractions are there but the faucet is limited to a drip.
