Oh, I miss del.icio.us - UI / execution / social discovery, all those fantastic finds... :) I love tagging a lot, but the problem with tagging is that only a handful of software/services use look-up for tag1 AND tag2 (AND tag3...) filtering. It's such a simple concept to filter all used tags based on already selected if I'm making a query using tags. I can not understand how people don't get that without this... - Source: Hacker News / almost 2 years ago
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 / over 1 year ago
