Wikipedia on "Value"

I just looked up Wikipedia's definition of "value" and found an intriguing collection of articles:

• Value (mathematics) -- the value of a variable in mathematics.
• Value (personal and cultural) -- the principles, standards, or quality which guides human actions
• Value (economics) -- the market worth or estimated worth of commodities, services, assets, or work.
• Value theory -- in ethics, aesthetics and other evaluative matters
• Value (marketing)
  
• Value (computer science)
• Value (law)
• Value (semiotics)
• Value (colorimetry) -- a measure of white or black in color

I think I'll take a good look at these and anything else interesting on the subject I can find—I'm thinking of writing a blog post series constellated around value as a central concept. It feels like that's the direction my thinking about identity is inexorably leading me, so I figured I might as well roll up my sleeves!
