There is also an equally powerful reason to add the old school MLM marketing approaches to your marketing arsenal. Reason #2 To Create a growth explosion in your group (The Big Al Theory) There was a series of books I read many years ago back in the Dark Ages of the network marketing industry (back when you bought actual paper books and studied doing things like Don Faila's famous "Napkin Presentations").
These books were called The Big Al series and were written about the teachings of a fictitious MLM upline called obviously, "Big AL. In one of the books he talked email list about using "Non-Duplicatable" marketing approaches to build a huge front line and then provide your team with "Duplicatable Approaches" to grow. Now I know that in the world of "Old School" MLM business development, its heresy to even consider using any approach that is not 100% duplicatable by your organization because the "Standard" (as opposed to Top Tier) Network Marketing Business Model relies on duplication.
The higher your duplication factor the quicker you get to the money. However the point the book made was that you could create an explosion in your MLM organization by using whatever unique marketing angle you wanted along with your personal skills to sponsor a ton of reps as long as you gave them duplicatable approaches they could use once they were in the game.
