Live Data Could Solve the Social Bookmarking Problem with Information Volatility
Alex brings up something in his Go and microformat stuff! covering what is in the works with Microformats at Microsoft. Scroll down to where Alex talks about "mRc = Live data wiring", now this live data access is incredibly important.
One of the elements that has been bugging me with social bookmarking it the volatility of the information is not taken into account when the bookmark is made. No, I am not talking about the information blowing up, but the blood pressure of the person bookmarking may rise if the data changes in some way. I look at social bookmarking, or bookmarking in general as a means to mark a place, but it fails as an indicator of state or status change of the information we are pointing to. The expressing of bookmarking and/or tagging is an expression of our explicit interest in that object we bookmarked and/or tagged. The problem is our systems so far are saying, "yes, you have interest, but so what".
What the live data approach does is makes our Personal InfoCloud active. If we could bookmark information and/or tag chunks of information as important we should be able to find out when that information changes, or better get an alert before the information changes. One area where this is essential and will add huge value is shopping. What happens with products in the real world? The prices change, they go out of stock, the product is modified, production of the product stopped, etc. The permeations are many, but those expressing interest should be alerted and have their information updated.
One of the things I have been including in my "Come to Me Web" presentations is the ability to think about what a person needs when they use and want to reuse information. We read about a product we desire, we read the price, but we may think about the product or put it on a wish list that is related to an event in the future. When we go to act on the purchase the information we have gathered and bookmarked may be out of date.
One solution I have been talking about in my presentations is providing an RSS/ATOM feed for the page as it is bookmarked so the person gets the ability to get updated information. I have built similar functionality into past products years ago that let people using data know when the data changed (e-mail) but also provided the means to show what the data was prior and what it had changed to. It was functionality that was deeply helpful to the users of the system. Live data seems a more elegant solution, if it provides the means to see what information had changed should the person relying on or desiring the information want it.
