Could be in the traditional sense (iGoogle, Netvibes, or other portal) or non-traditional sense (my e-mail or Flipboard or Facebook/Twitter is my start page) though doubt the traditional sense is relevant to HN.<p>Inspired by: http://clintonwu.com/post/10445425917/death-of-the-personal-start-page
My current start page is google with instant on. But, interestingly, it used to be mint.com. I became very addicted to mint for a period of about 3 months. After that initial phase, I never used it again. Maybe I burnt myself out.
