Most of us who live with children and computers know about software for controlling how the former use the latter. But what about the grownups who can’t control themselves? For adult Internet users ready to admit that they’re in the grip of a higher power, there is Covenant Eyes, a website that will keep track of all the other websites you visit—and e-mail this potentially incriminating list to an “accountability partner” of your choosing. Covenant Eyes even rates websites on a kind of taboo scale (the higher the score, the raunchier), so that your spouse or pastor can tell at a glance whether you’ve been poring over market research online or taking in a peepshow.
