  9. Track evolution over time • What is changing about interest in Stem cell research/GM food? • Are experts good at identifying changes in public interest? • How can experts be sure/can they be supported with quantitative information? • Can blogs be used to generate time series reflecting changes in “public interest”?

  10. Free science debate graphs • Solves the trend identification problem? • Blogpulse Offers free automatic blog searches and keyword-generated click-search graphs • Stem cell research • GM food • Mobile phone radiation

  11. Research graphs • Time-consuming to collect data • Give control over the data source
