The value of web 3.0 will be in its content, not in the technology to deliver it. To succeed, a company must make extremely efficient use of techonology for delivery, and focus on valuable content resources (people).
As with everything, the web is becoming increasingly specialized. Pure social networks that are intended to serve as resources will be replaced by managed content systems where the bulk of the material is posted by professionals and site visitors will offer supplementary content.
There are great opportunities for building sites of user contributed content, but the users should be qualified, and they should be rewarded with some benefit. An example would be a teachers’ system. Teachers (who are intelligent, resourceful, and creative) can share materials with other professionals in the education field. Their contributions can be rated, and those ratings can be used to offer items of value. For example, gift cards to stores that offer products they may appreciate - either personal or professional. In this case, the producers and consumers are from the same population. Another module could be to have medical professionals offer content for the general public. These are just examples.
The platforms these are built on must be extremely robust. The software itself is actually of limited value - it is only important to deliver the content, but that content must be protected, and preserved. This requires a careful storage architecture that should be portable.
