The timeline briefly documents key IndieWeb terms/ideas/concepts, implementations, specifications, and other achievements; people involved, and dates/URLs for each.

In every case, a source pointing to an exact date or community verification should be used.

Key (in rough order of how ideas develop, succeed)

  • (C) - Conceived. Concept/idea presented, published, discussed.
  • (T) - Terminology proposed/defined. Naming things helps talk about them (so says @timoreilly, Brooklyn Beta, 2013[1])
  • (E) - Event. In-person notable/significant meeting/event that furthered the Indie Web.
  • (I) - Implemented. Implementation shipped and deployed live and working on a personal indie web site.
  • (L) - Launched. Site, service, or software launched.
  • (S) - Specified. Specification written down and publicly published on the web.

Note: Below is a draft of unorganized data with rough dates. Needs cleanup. Source: @caseorganic conversation with @t, IndieWebCamp UK 2013-09-08



Rise of Pingback Spam

Decline of Personal Sites

  • Distracted by RSS/ATOM wars, blogs began to decline
  • Hosted blogs, people turned to social networks more than blogging
  • Eventual fade of RSS/ATOM

2010: State of Blogs

  • Not much personal blog activity
  • WordPress heavy and dominant


  • Github hosted blogs, Medium for frontpage Hacker News

Siloed blogging and writing frameworks.

  • MEDIUM: Don’t claim ownership but reserve the right to use your content even if they get acquired in the future.
  • Wikia: Communities don’t own their content and can’t transfer it off their site.

Differences between 2013 and 2003

  • Short status updates became an acceptable form of content
  • Easy enough to show an entire conversation or a link to another page

2011 (E): IndieWebCamp Conf

  • Purpose: Show, don’t tell
  • Builders Only. Must have your own domain name and actively build stuff for it to attend.
  • Use your domain name and OpenID to sign into the IndieWebCamp MediaWiki. http://indiewebcamp.com/
  • Could only add self to the attendee list if you use your domain name to log into the site.


  • IndieAuth implemented on IndieWebCamp.com (replaced OpenID)
  • 2012-06 (E): IndieWebCamp2012: changed from Builders-only to Creators-only to more explicitly include UX+design
    • Again, could only add self to the attendee list if you use your domain name to log into the site.
  • Domain Name, rel=me, mediawiki
  • 2012-09 (E): IndieWebCampUK 2012 (first in the UK)
