My memory's not great, and it's good to be able to double-check if I've talked about something with someone before, or to find old links/information shared ("damnit, what was her niece called again?

Or stuff like "remember when you told me X?" - just to have evidence to clear things up, or to be able to refer to conversations in the distant past from time to time.
