A bit of context for Mine!:
It comes down to whether you prefer context to be provided by:
1. automated algorithms a la Google and the thousands aggreation sites,
2. trusted sources including vendors, manufacturers, even third parties and intermediaries, or
3. your network of friends aka social network
The answer is obvious.
It depends! We use all three at different points in our information gathering, sharing and exchange and transactions. The challenge for VRM is to understand advantages and disadvantages of all three and encourage development of tools that give me, the individual user or customers, the best of all three.
My bet is on no.3. I want to help individuals to capture both data and context on their own terms. This will give rise to another layer of knowledge that serves both the individual and his network. For example, I want to collect data about my shopping, with my own comments and with sources of information useful to me. I want to have pictures of products I have bought, links to reviews by others and my own, comments by friends in my network, record of interactions with the vendors and third parties etc etc. I want it in a place I can further analyse it and share it based on my privacy requirements.
With time, all this can become a source of better understanding of my own behaviour and preferences, and, with practice, a better negotiating position in future transactions. In other words, I will be the most authoritative source of my own history, with data, information and knowledge about me.
