Jamie Notter doesn't seem bothered by Twitter users posting tweets about what they will eat, are eating, or just finished eating for lunch. He equates it with observing an officemate carry fast food through the corridor in a bag that identifies its point of origin.

The tweet just tells you what you would have seen had you been there.

Some folks lament the reliance on social media, feeling it takes the place of personal contact. In fact, it is really an attempt to fill the gap already left by lack of personal contact.

In a way, it's like writing letters. You'd rather be with someone, but you can't. So you write to them (or tweet to everybody).

But do you really need to write so often?
