  1. Traffic Characteristics and Communication Patterns in Blogosphere By Fernando Duarte, Bernardo Mattos, Azer Bestavros, Virgilio Almeida, Jussara Almeida Attacked by Ionut Trestian

  2. Introduction – What are we looking at? (I)

  3. Introduction – What are we looking at? (II) • The paper will try to trick you with big numbers • 200,000 distinct blogs out of an estimated of 60,000,000 world blogs in 2006. • That’s 0.33% • Population of Brazil: approx 200,000,000 • That’s 3.33% out of 6,000,000,000

  4. Motivation (I) • At least the authors don’t give the usual motivation: - “blogs important in politics, economy etc” • This would actually be hard in fact of the figures we showed earlier • Motivation is to study how blogs impact traffic

  5. Motivation (II) • Traffic engineering • Traffic engineering ??? • Last time I checked ISPs were more worried about clients doing streaming and costly downloads • Or you want to kill the problem from its source?

  6. Burstiness of access patterns ?

  7. My point? • The observed burstiness probably comes from external factors – events that trigger users discussion/information sharing • But the paper never tries to correlate the observed behavior with these facts …

  8. Search engines (I)

  9. Search engines (II) • Why change search engines by incorporating social information in Page-Rank? • Search engines and Social Networks have 2 different functions: • Search engines: finding content • Social networks: finding what my friends are doing • Imagine social networks as being bookmarks to your friends

  10. Search engines (III) • How do people who read get to these different types of blogs, isn’t that important? • Broadcast probably list links to content • Parlor is where the discussions take place • Register ?

  11. Search engines (IV) • Also the authors never mention what attracted the search engine users to the blog in the first place • Finding content – rapidshare links • Getting tricked – spam • Conclusion • Terrible idea • Most search engines ignore blogs anyway • Makes sense to have both just the same way as most people use both bookmarks and search engines

  12. Distributions (for Gregory)

  13. Conclusions • Motivation – almost non-existent • Their Applications even more so … • Generating blog traffic • Modifying existing search engines
