Why do you care what people name their Emacs config? One advantage right of the bat with a unique name is for referencing a configuration to new users to get up and running on Emacs quickly, instead of:

1: "Hey try this configuration until you're up to writing your own."

2: "Which one?"

1: "my .emacs"

Rather than being able to Google: "Emacs Prelude" or "Emacs Starter Kit".

As for educating new users, most people simply don't have the time or regard to build an Emacs configuration that they can be productive with right away from day 1. There's just too much to know all at once. Emacs configurations such as the Emacs Starter Kit and Prelude provide a centralized place for new users to learn. I see how configurations can do anything to increase the confusion they already have. They either don't care and just like how it works better than without the configuration, or they're interested and use THE manual by doing the C-h's, or browsing the configurations files learning new things incrementally, when they feel like it.
