I was thinking on the same line, to dump all the personal memories into cloud not just anniversaries and birthdays but also what I promised to others and what I observed or any decision at work so that later I can back myself up with data. Its like a personal journal in case my memory becomes weak. There are things like evernote but they are more of a active notes which you open sometimes infront of others or while screensharing. I wanted something like Date wise or tag wise. It will be great if this can have a timeline. I also thought of making private facebook posts but for obvious reasons its not a good idea.
