Edit: changed "efficacious" to "effective" because oh my god why did I use that word.
1) I think there's a strong case to be made that says spending 10 seconds thinking up a story is much more efficient than stopping a conversation, opening an app, and typing in details on a touchscreen.
2) if we offload everything, what are we saving? Assuming it takes just as long to make up a quirky story as to tap in someone's details[1] what have you saved, except possibility the opportunity to exercise mental skills otherwise falling into disuse?
IOW: If we offload everything, we become glorified mental button pushers.
---- The landing page is actually well done - simple, to the point shows and tells me what it's about without a ton of wasted space.
That said: it looks like a lot of steps; and it doesn't give you any way to associate the face. Seems like you come away with a list of people you've met in reverse chronological order, but nothing that really says "This person I see before me now is Hermione".
