It isn't literally everything; there are some heuristics to detect what was interesting to you. I understand you might find this excessive. I routinely find that useful. :) See also "As We May Think" by Vannevar Bush. > and it is terribly inefficient to store say, 30,000 examples of the exact same article ... You're right: no deduping is and can be done across users (HMACs chained up the user's password are used create dedup hashes). Storage is sufficiently cheap that I feel it's a acceptable tradeoff vs. privacy (i.e., server being unable to confirm that two users have saved the same page).
