In some communications, the sender is the message. Their identity, preferences, daily activities, and opinions are given. The pressing question of "which marsupial do they most resemble?" is answered. Potentially, their expertise is used to provide useful information (or misinformation) that comes uniquely from them.
This, then, is selfcasting.
This blog is an example of selfcasting, in which I try to exercise my always-in-development quasi-expertise to look at varying issues out in the world, and come up with interesting opinions to think about. A facebook profile filled with feeds from Twitter and Yelp, where the location, activities, and texted conversations of the user are posted, is also an example of selfcasting. The guy at your office who must show you pictures of his vacation is selfcasting.
Selfcasting is done for a whole host of different reasons. From the viewpoint that this blog is tossing around, one of those reasons is universal: People selfcast to get their ideas and language, their views on the world, out where they can be absorbed and interacted with. We share pieces of our identity, ranging from the deeply-considered to the entirely trivial, into a place where those things can spread and be negotiated. And, yes, we're looking for recognition, status, and acceptance when we selfcast - this isn't some special exception from the basic need for social validation.
Online, selfcasters often track the number of people reading or viewing their content (I use google analytics). We care about the engagement of the audience, in the form of comments and incoming links. Some selfcasters pile in advertising and other such on their blogs, adding a money motive on top of this, but the social motives never go away.
So, in a bald bid to see if folks are engaging here, and to give you an opportunity to put your own stuff out there a little...
Do you selfcast?
