Very interesting idea, simple, but the first site like it I have ever seen.
I would have liked a few features that maybe we will see when the premium version becomes available.
Some features I would have liked to see:
-Custom questions that get asked about everyone, not just the one person.
-Questions involving siblings.
-Custom questions that lead to other questions (ie a custom question flowchart)
-questions involving holidays, first everythings like first job, first xmas that they remember, etc.
Overall, a great idea with potential!
