Reddit mentions of Helvetica

Books books books!

Some essential reading:

• Thinking with Type - very basic, and a good place to start; designed like a workbook
  
• The Elements of Typographic Style - pure reference
  
• The Vignelli Canon (PDF, also available as paperback)
  
  You have probably heard of the documentary Helvetica. This movie inspired me to become a type nerd. The follow-up movie, Objectified, is also very good and focuses on consumer design.
  
  Web sites / blogs:
  
  
• Typophile - active forum and community
  
• I Love Typography - great blog
  
• The Ampersand - pictures of ampersands; more interesting than it sounds
  
• Brand New - logo design, not typography specifically
  
  If you are at college or have a college campus nearby, check our their art library. There are bound to be awesome resources there. Explore graphic design periodicals and get lost in giant bound books of type samples.

What about this?

I hope to god you've seen this!

The Helvetica documentary? It is quite interesting even if he does not like the actual font. Link if you want to buy it: http://www.amazon.com/Helvetica-David-Carson/dp/B000VWEFP8

Not me...I'm watching Helvetica

If you are interested in product design, graphic design, and art, Objectified and Helvetica are great documentaries about the relation people have to the way things look and feel and how designers choose these properties for their products.
