On “black Friday,” I didn’t stand in line at 4 in the morning for a $99 Blue Ray player, nor did I run through Walmart aisles on my way to a $9 toaster.

But I did venture out in search of a new computer for the family – preferably one that doesn’t spontaneously shut itself off in the middle of a writing project.

While in the “big box” venues of high dollar electronic consumerism, I noticed that the sales clerks seemed very connected to their jobs – literally. Various cellular communication technologies seemed to be giving the sales team instant access to management, the stock room, the affiliated store across town, and even to customers who were considering coming out to the store.

The New York Times noticed all the technology and social-media interaction going on:

Once upon a time, people mailed their holiday wishes to the North Pole and hoped for a reply on Christmas Day. Nowadays they are sending their wishes into cyberspace and are apt to get a reply in minutes.

America’s first Twitter Christmas got under way in earnest on Friday. Across the land, retailers and their customers used the social networking site to talk to one another about bargains, problems, purchases and shopping strategies.

In Bloomington, Minn., Mall of America used its Twitter page to tell consumers two of its parking areas were at capacity and that their best bet was to park near Ikea. Twitter permits public communication via short, to-the-point messages. Many people use it to send mundane updates to their friends, but increasingly, the nation’s retailers see it as a business tool.

Did anyone else notice this while out shopping?
