  • Ask HN: Is there a spiritual successor to del.icio.us?
    Https://diigo.com It's less simple than Delicious used to be, but it scratched the itch for a while for me. I barely ever bookmark anything these days. When Delicious was sold I stopped using it, and realised I didn't miss bookmarking and hardly ever read any of my bookmarks anyway. Excessive bookmarking seems like FOMO to me, I try to avoid it and embrace a more Zen-like attitude :). - Source: Hacker News / almost 4 years ago
