I'd pay for a list of bookmarks from various opinion leaders. If george soros or andreesen bookmarked on a consistent basis content that they read or think is important to read I would be interested in that. What would be good is if they also included a short commentary of the importance.<p>The value to me is I can get a feel for what some of the most influential people are interested in and what specific information they are using to shape their opinions on various topics.<p>Twitter is some what like this, but there needs to be good consistent content.
