A front end DEV is akin to a witnes that supports the chain by hosting under their own name or corporate entity. Such DEVs would support onboarding and community development. Can create their own trafficking and Ad placement if they like.

In short: you need more than a graphene chain to make a social net work. Blurt is just a white lable, open sourced, flat database. It requires a few extras provided by Real Devs to succeed rightly.
