VU will survive in some warped evolved existence with the change in times since its inception 2004. Highest failure would have been in its formative 5yr probationary window. Yet it managed to survive and now going into its 15th year? Despite its broken features, lack of communication and connection, out of touch with its users, surviving settlement lawsuit over, change in leadership, its few competitors. They have managed to maintain a profit and users are willing to pay, simply by providing a value users are willing to use, thus keeping them in business. It is a value which is just enough to keep users happy and willing regardless of the many exiting and complaints.
However, i do believe that could be their possible downfall. Once they no longer provide the value it could easily teeter into a shutdown. The loss of users outwaying the actual users.
