The summary is the most value part since it shows the top 10 discoveries that the tribe thought the most relevant to solving that problem. It can be seen as an accelerated solution to that problem space, based upon the opinion of the tribe.
The summary is a living document and changes as the Tribe comments, votes and adds opinion.
In the short term the owner of the journey can also rate his or her own summaries. Should the owner be the only user in that journey, it will give him or her the ability to "manipulate" the summary outcome based upon their own preferences.
These summaries are the digests of relevant information that TribalMind will use to teach others as well as remind you of key points.
At a future stage, these summaries will also allow you to earn "currency" within TribalMind to allow you to buy certain virtual and physical goods.
