Web 2.0 came to represent emerging phenomena and trends on the Web. "Basically… the proliferation of interconnectivity and interactivity of Web-delivered content."
Of historical interest:
- Etymology, etiology? It began as a buzz word, and came to represent significant insights into recent trends…
- Enterprise 2.0
- Government 2.0
- Library 2.0

Mess to digest:
1. Web 2.0: content
- User generated content (UGC):
- Item (by effort): rating, bookmark sharing, comments/talkbacks, tagging, forum messages, blog entries, Wiki pages, multimedia.
- Collection, filtering, or processing of content.
- Collective intelligence
- Blogs: huge phenomenon, democratization, diversity, credibility, hyperlinked communities…
- Open standards
- Open APIs
- Open source (FLOSS)
- Folksonomies: freely chosen keywords — not controlled vocabulary.
- Data lock-in
- Rich Internet applications (RIA): user interfaces (UI), user experience (UX); eg, AJAX.
- Mash-ups, syndication, right to remix.
- Small pieces loosely coupled, granular addressability.
- Hypertext, hypermedia? (Eg, non-linear?)
- Semantic Web, aka Web 3.0
- Web as platform/SDK
- Convergence, software above level of a single device.
- Components (small pieces loosely coupled)
- Hosted services, software as a service (SaaS).
- Open standards, APIs, open source, hackability.
- Fight the Internet?
- Perpetual beta: always updating, launch then iterate. "Release early and often" [FLOSS moto].
- Virtual worlds?
- Hypertext? (Trackbacks, blogrolls? But, not new — Web 1.0?)
- Lightweight user interfaces (and development models, and business models).
2. Web 2.0: Social
- Active users/clients — participation:
- Sharing; eg, Wikipedia, blogs, Flickr, YouTube, BitTorrent.
- Personal publishing; eg, blogs.
- Trust users: as developers, contributors; eg, PageRank, reviews, reputation.
- User generated content (UGC)
- Democracy. Eg, corporate media vs independent journalism — Indymedia.
- Groupware, aka CSCW; eg, Wiki.
- Distributed independent developers, especially open source.
- Peer reviews
- Collaborative editing, ranking, folksonomies (aka collaborative classification, social indexing)…
- Social networks (FOAF...)
- Global audience/market
- Perpetual beta?
- Virtual worlds?
(Split to several (sub-)topics?)
3. Web 2.0: value
- Network effect: effect that usage of a good or service has on its value to other users.
- Eg: telephone.
- Related concepts: positive feedback (loop), bandwagon effect, critical mass, saturation, peer-to-peer.
- Separate from effects of economies of scale, mass production, safety in numbers.
- Long tail: combined volume of niche markets larger than mainstream.
- Self-service enables leveraging the long tail
- 1M sites with 1K users is more than 10 sites with 10M users.
- 10K bands selling 5K albums, not 50 bands selling 1M albums.
- AdSense, affiliate models…
- Few blogs have lots of in-coming links, most only a handful.
- "products in low demand or… low sales volume can collectively make up a market share that rivals or exceeds…"
- "We sold more books today that didn't sell at all yesterday than we sold today of all the books that did sell yesterday." [Amazon]
- Software as a service (SaaS), not packaged software. (Requires cost-effective scalability.)
- Freemium: services are free (gratis), then "premium" (aka up selling).
- Fast distribution of content
- No censorship
- Data lock-in: control over unique, hard-to-recreate data (that gets richer as more people use them).
- Lightweight (software) development models
- Emergent user behavior, not predetermined
- Harnessing collective intelligence
- Added value is essential in SaaS, RIA. Eg, Gmail, Google Docs…
- Mashups and syndication — lightweight business models
- Innovation in assembly: value in aggregating, managing, analyzing complexity.
- Distribution, development, and architecture of participation (AoP) mean new generation of lightweight competitors. (?)
