Oh, I'm sure I have it saved somewhere, but your point is apt: if all you remember is the general concept, but none of the key phrases used, nor a specific enough timeframe, when you've been saving things about wearable computing for fifteen years (as I have), how do you find it? I don't know that that's a solved problem yet.

At least, it would only be fifteen years of personal saved items to go through, instead of the entire internet.
