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)
