It is clear that Americans' attention spans are rapidly shrinking.
An example...here is how I 'read' the newspaper.
First, I read it online. I simply scan the headlines. Once in awhile, I click on the headline and read the first couple paragraphs of the article. I rarely complete an article, especially if it is more than one page. I do check the local and national news sources. Worse, on msnbc.com, I often will click on a video story so that I don't have to expend the energy to read.
I also double up on entertainment and information (e.g. The Daily Show, Chesley Lately, and Wait, Wait Don't Tell Me). I do lay in bed each morning listening to NPR.
This trend is obvious in the decline in the blogosphere and the increasing popularity of Facebook, Twitter, and text messaging. Clearly, I don't blog as often as I used to (this due to several factors). I rarely get regular emails but I have lots of activity on Facebook (which I check several times per day). I, personally, haven't moved onto tweeting or texting but it will happen.
So, is this a negative trend? I don't know. I definitely feel more connected to friends and family through Facebook. I know what is happening in their daily lives and know when people have birthdays, babies, parties, tragedies. My parents aren't on Facebook so they miss out on cute things the kids do and photos since I don't blog about them anymore (hint, hint).
