  4. Where is P2P? • P2P has been around for years (Generations of) Researchers have worked on P2P… • … and tackled some problems we wouldn‘t have had without them …  P2P matured and ready-to-use?!? But: Somehow P2P not catching on in the „real“ world • Perception still dominated by early file-sharing systems, e.g. Napster… • … which isn‘t even a P2P system after all… • … and has gained negative reputation • … due to legal issues (P2P = Pirate-to-Pirate) Why P2P Sucks... at least a bit

The Quest for the „Killer Application“ • P2P Sales Pitch – No central entity, privacy, anonymity, … • Service Providers: not really intriguing as a business model If nobody „offers“ it, people need to run it themselves… P2P Showcase: Web Search • Users: Google is doing a pretty good job(not only because they are sponsoring this conference…) • Missing incentive to use P2P Web Search! • Incentives and Business Model: Two sides of the same coin • Business Model is Incentive for Service Providers Why P2P Sucks... at least a bit

  7. So why did file-sharing catch on? • Napster / Gnutella / Kazaa caught on because users couldn‘t access data otherwise (at least not for free) Why P2P Sucks... at least a bit

  8. So why did file-sharing catch on? • Napster / Gnutella / Kazaa caught on because users couldn‘t access data otherwise (at least not for free) • Napster / Gnutella / Kazaa didn‘t lastbecauseusers couldn‘t access data otherwise (at least not for free) • Music Industry doesn‘t like it… Insight: Web Data is freely available – no user incentive?!? Why P2P Sucks... at least a bit

  9. So what does it mean for P2P (Search)? • P2P Killer Application requires incentives • Possible User Incentive: Improved Web Search Experience • „Social Search“ on Intellectual Input of User Community • … that users wouldn‘t be willing to provide for commercial purposes Wikipedia • Possible Service Provider Incentive: • non-free original data • Business Peers run network in order to sell their data…… they would be willing to give out for indexing otherwise Why P2P Sucks... at least a bit
