Left to my own devices

Perhaps you've the seen the signs? Various advertising billboards around town have sprouted-up, attempting to make a connection with a static object and a live social media account. This is a product of Adams Outdoor Advertising Company, and they even have a web site devoted to it. Here they tout one of their more pronounced billboard messages: 'Our first tweet was hand-painted.' They go on to explain how they come to equate their business with that of social media:

"Are you an introvert, or an extrovert?" This question is sometimes posed to folks, by those who do not know them very well. At times, it's a question some turn inward, asking it of themselves. I know I do. Is it really important? Do we really need to ascribe labels to an aspect of our personality? Perhaps. Labels help define us. But are they also a hinderance? If we are considered by others (or by ourselves) to be either shy or outgoing, does that in-turn shut down further avenues about us that could be more deeply explored? Is this why we place such self-importance on what kind of person we are in social situations?
