Jeremy Liew writes a post demonstrating the wise use of attention data, and adding value to users. I've been critical of many viewpoints on the "attention economy" (see my post regarding virtuous profiling and the implicit web), but Jeremy echoes the sentiments I wrote for how implicit profiling ought to be done for user value:
This is a good example of attention data in action. Some people call it the implicit web. There are three reasons that this creates a good user experience:
1. It requires no effort from the user (because it uses implicit metadata that is gleaned from watching normal activity)
2. It is presented contextually (so you’re not overwhelmed with data when you don’t need it)
3. It informs decision/actions that the user might take.
The only thing he misses is the importance of privacy controls, but that was due to the context of his post. In a company like Others Online, clearly he'd see the importance of user privacy controls.
