Wasted Memories

My research
It made me realise how important those little memories are, how important it is to document and record our everyday lives. Lots of people do it, in form of photographs but they are consciously remembering the things that they wish (or think they should) remember. The memories me miss are the ones that we think are unimportant, the memories we collect unitentionally (unconsciously). The ones we throw in the bin, the ones that we think are waste. The day to day memories we create without thinking about it.
What could we do to make sure we capture those memories? Instead of throwing them away, could we in some way encourage people to keep them?
We may not want to keep those memories ourselves but as human beings we are designed to be intrigued by other people and their lives. We love to speculate and know what other people are doing. Could we in some way encourage people to display their memories for others to see. A way in which people can throw away their memories but they are not wasted.
