No really, what is it?

  3.0 is for machines and connections between data
  (for the benefit of people)

Or my favorite

  question when you dont know what to ask for.
• BUT, Its also a fluid, evolving concept rather
  than an integrated working system.

The Jargon

  every thing has a standard name and a permanent
  place to be referenced
• RDF and OWL language and syntax to describe
  relationships between things (incl. ontologies)
• GRDDL gleans and extracts RDF data from web pages

Okand?

• Adding Semantic flavor to your site involves
  adding machine-readable metadata to content that
  give relationships and meaning.
• It could involve tagging on the backend or the
  public site

9
Why should publishers care?

• It allows servers to find, extract, share and
  re-use information.
• It gives context to the tags in your articles and
  allows you to do more with your content without
  human effort, like build up an index of people or
  call up a map with the mentioned locations
  automatically
• It helps search engines deliver more relevant and
  accurate results
