Literary Discussions

It suddenly occurs to me that "good fellowship" almost always implies among the like-minded, which is interesting if we think about how we "silo ourselves" and as Paul says "avoid vain disputations" ... I wonder if Facebook might ever be described as "fellowship?"  When we cloister ourselves with only the like-minded we never change, we never grow or diminish, but I suppose the idea is to "keep the faith" (whichever one true faith that may be.)
