Web shortcomings and opportunities

There is a very interesting post itemizing some of the perceived shortcomings of the web over at the SpaceCollective.

Some of those problems have been addressed by researchers in the past - notable examples are Freeman and Gelernter's Lifestreams, and Nelson's transclusion (I assume this is what the author of the SpaceCollective article means by the term collage; in any case you can start using a limited form of transclusion today).

Some of those problems are being addressed on an ad-hoc basis by commercial companies today. If you take some time to think about the problems, there is still a wide open field of opportunity to provide commercial offerings around the ideas there.
