On public displays of affection -- but not that kind

Today, we send and receive notes publicly in a way that seems shocking when viewed by communications standards just a decade ago. Expressions of friendship, social plans, etc.

“I miss you!”...
“Hey, are you going to Fred’s party tomorrow?”...
“Save me a dance this Wednesday!”... etc.

Why do we like this, why do we post rather than e-mail? Bonding? Convenience? Insecurity? Is it just an extension of the old “You’re the greatest!” scribblings we got in our high school year books? :-)

I feel torn about this.

On one hand, I must confess to being oft-delighted by both the chance to quickly share warm feelings or make arrangements with friends and acquaintances all over the world, many of whom I might not otherwise have a chance to more formally or personally converse with.  But on the other hand, this almost seems like a narcissistic and lazy version of friendship, and a behavior that’s not particularly seemly in someone who is nearly four decades old.

I’m almost past feeling bad about not handwriting letters anymore.  I still feel awful that I have unreplied-to e-mails in my inbox from dear friends that I’ve put off for “when I have time,” yet here I am writing a blog post.

Have we become a culture of relationship snackers?  Has the ease of publishing, of communicating, of virtual hugging (not to mention cow-throwing) resulted in an exciting and perhaps overall-positive broadening of our social circle… but at the expense of deepening relationships?

What do you think?  Why are we so drawn to this micro- and public communicating?  What does it mean for us?  What does it mean for relationships?
