Web 2.0

Web 2.0 came to represent emerging phenomena and trends on the Web. "Basically… the proliferation of interconnectivity and interactivity of Web-delivered content."

Categories:

  1. Content
  2. Social
  3. Value
  4. Open source

Of historical interest:

  1. Etymology, etiology? It began as a buzz word, and came to represent significant insights into recent trends…

1. Web 2.0: content

Data/content perspective:

  1. User generated content (UGC):
    1. Item (by effort): rating, bookmark sharing, comments/talkbacks, tagging, forum messages, blog entries, Wiki pages, multimedia.
    2. Collection, filtering, or processing of content.
  2. Collective intelligence
  3. Blogs: huge phenomenon, democratization, diversity, credibility, hyperlinked communities…
  4. Open:
    1. Open standards
    2. Open APIs
    3. Open source (FLOSS)
    4. Folksonomies: freely chosen keywords — not controlled vocabulary.
    5. Hackability
  5. Data lock-in
  6. Rich Internet applications (RIA): user interfaces (UI), user experience (UX); eg, AJAX.
  7. Granularity:
    1. Mash-ups, syndication, right to remix.
    2. Small pieces loosely coupled, granular addressability.
    3. Microformats?
    4. Hypertext, hypermedia? (Eg, non-linear?)
  8. Semantic Web, aka Web 3.0
  9. Web as platform/SDK
    1. Convergence, software above level of a single device.
    2. Components (small pieces loosely coupled)
    3. Hosted services, software as a service (SaaS).
    4. Open standards, APIs, open source, hackability.
    5. Fight the Internet?
  10. Perpetual beta: always updating, launch then iterate. "Release early and often" [FLOSS moto].
  11. Virtual worlds?
  12. Hypertext? (Trackbacks, blogrolls? But, not new — Web 1.0?)
  13. Lightweight user interfaces (and development models, and business models).

Notes

(None.)

2. Web 2.0: Social

  1. Active users/clients — participation:
    1. Sharing; eg, Wikipedia, blogs, Flickr, YouTube, BitTorrent.
    2. Personal publishing; eg, blogs.
    3. Self-service
    4. Trust users: as developers, contributors; eg, PageRank, reviews, reputation.
    5. User generated content (UGC)
    6. Democracy. Eg, corporate media vs independent journalism — Indymedia.
  2. Collaboration:
    1. Groupware, aka CSCW; eg, Wiki.
    2. Distributed independent developers, especially open source.
    3. Peer reviews
    4. Collaborative editing, ranking, folksonomies (aka collaborative classification, social indexing)…
  3. Social networks (FOAF...)
  4. Global audience/market
  5. Personalization?
  6. Perpetual beta?
  7. Virtual worlds?

Notes

(Split to several (sub-)topics?)

3. Web 2.0: value

  1. 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.
  2. Long tail: combined volume of niche markets larger than mainstream.
    1. Self-service enables leveraging the long tail
    2. 1M sites with 1K users is more than 10 sites with 10M users.
    3. 10K bands selling 5K albums, not 50 bands selling 1M albums.
    4. AdSense, affiliate models…
    5. Few blogs have lots of in-coming links, most only a handful.
    6. "products in low demand or… low sales volume can collectively make up a market share that rivals or exceeds…"
    7. "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]
  3. Software as a service (SaaS), not packaged software. (Requires cost-effective scalability.)
  4. Freemium: services are free (gratis), then "premium" (aka up selling).
  5. Fast distribution of content
  6. No censorship
  7. Data lock-in: control over unique, hard-to-recreate data (that gets richer as more people use them).
  8. Lightweight (software) development models
  9. Personalization?
  10. Emergent user behavior, not predetermined
  11. Harnessing collective intelligence
  12. Added value is essential in SaaS, RIA. Eg, Gmail, Google Docs…
  13. Mashups and syndication — lightweight business models
    1. Innovation in assembly: value in aggregating, managing, analyzing complexity.
    2. Distribution, development, and architecture of participation (AoP) mean new generation of lightweight competitors. (?)
