Web 2.0 Overview
The combination of online social networks, folksonomies, web content, and content hackability / reuseability
Buzzwords: Wiki, blogs, RSS, Open / web APIs, perpetual beta, tags, some rights reserved, the long tail, badges, network effects, ratings, OpenID
Definitions
Social network – online social structure made of nodes which are individuals
Folksonomy - collaboratively generated tags that categorize Web content
Hackability / reuseability – content viewed in one online location but created / hosted elsewhere; components of a mashup
Definitions (con’t)
Wiki - a website that allows visitors to easily add, remove and edit content
Some rights reserved – allow hackability and remixability without allowing pure resale
Network effects – the value to a potential customer of the number of customers already using a service
Definitions (con’t)
Ratings – Content valuation based on explicit (member provided) and implicit (centrality eigenvector) scores
OpenID - a decentralized digital identity system
RSS - a simple XML-based system that allows users to subscribe to online content
The Long Tail
A statistical distribution where the low amplitude population outnumbers the high amplitude population
Many small groups can be more profitable than a few large groups assuming a low group acquisition and maintenance cost
