What if Facebook felt less like a daily diary and more like an autobiography? It might resemble Proust, a new site that lets you record and share a lifetime's worth of memories. Proust prompts you with questions such as "How did you break the news of your engagement to your parents and parents-to-be?" and "What was your first boss like?" You respond with words, photos and videos, and choose whether they're private or public. Little by little, you reconstruct the story of your life and if your family and friends do the same, you might learn new things about people you thought you knew well.
