Hierarchy of Contact

In the digital age we all have a multitude of options for communication. It can be inferred that there is a kind of "Contact Hierarchy" and "Contact Continuum" as not all modes hold the same weight with communication ranging from 1-10. Hierarchy of contact in 2010 as defined by this contributor: 1. Face to face 2. Telephone 3. Personal Letter 4. SMS, BBIM 5. Email 6. Personal message eg FB 7. Instant Message eg FB, MSN 8. Wall postings, comments 8. "Like," "Poke" 9. Nil contact. 10. Active blocking of contact. Note: Higher order = increased responsiveness. A more serious and/or important matter or message would attract a higher order of communication, with the top order being face to face. There are so many ways to communicate, the options are greater than ever before. But is all modes of communication the same, and attracting the same weight of force? Therefore there is a hierarchy. This may vary per user, but there is a hierarchy.
