Recently I have been working to minimize distractions and increase motivation through a number of steps. One step I took was to block a number of domains Sunday through Friday. Www.youtube.com was one of said domains and doing so opened my eyes to just how pervasive YouTube embeds are on internet.
I challenge HN readers to block one or more domains for 24 hours. You will quickly notice just how often the blocked tendrils will leave blank/broken areas in sites.
A few good domains to block are www.facebook.com, www.youtube.com, twitter.com, or even just flash completely.
