This turns Tumblr users into editors and curators in addition to content creators. The sharing functionality allows posts to spread rapidly, just as links and headlines do on Facebook and Twitter. In Tumblr’s case, though, the whole post is shared, not just the headline and link.

It’s worth noting that this whole concept makes a mockery of the idea of traditional content “theft.” If someone “re-blogged” a traditional newspaper story, inserting it into their own site, the newspaper would probably scream bloody murder and sic lawyers on them. And yet, on Tumblr, those whose posts are “re-blogged” feel nothing but gratitude and pride (thanks for sharing my work!).

Some other interesting facts:

  • The average post is “re-blogged” 9 times
  • 90% of the posts on Tumblr are reblogs or groups (curation). 10% are original content creation.
We agree to all the points except for the pair “relevant - usefull”. Relevance is depending on the interests and the actual context of an individual content consumer. Whether the content is usefull depends on the value it carries for the individual reader, but again does not depend on the format.
