The eternality of information is the building block of the association. It is an idea that breaks down the fixation on the present and turns time into a seamless whole. For all its conceptual beauty, there are weaknesses to Lifestreams that stem from its neutral and featureless view of time. Every page looks the same. Every stream flows in the same way.
Every year looks the same as another.
This seems at odds with human perceptions of time, in which some moments are more significant than others, some years more action packed and memorable. It also produces a natural clumping of information that may not fit into folders very well but doesn't just lie there hanging around either. What I think is lacking is a way to show the full landscape of rivers and rivulets, and the natural clumping of some events into ponds and lakes. He has also been thinking of ways to highlight sub-streams so the grouping of some events is more apparent. But what is clear from their ideas is that traditional methods of perceiving information will be dead in future.
