At 90, Chandler Murray's mailbox, not counting bills and solicitations, receives only a handful of seasonal letters from a few old friends. "People just don't write letters anymore," says his daughter Heather Bellanca. And by people, she means anyone more than 20 years younger than Murray, who lives by himself in Middlebury, Vt.

So how does The Associated Press define proper Twitter usage, and what new ammunition do grammar trolls have for assailing would-be Twitter commentators?

An executive loses his job and despite 25 productive years, he tells himself: I'm a loser. I can't provide for my family, and I'll never be able to again.

An eminent scholar is offered a top post in the Obama administration and his first reaction is: They must have made a mistake.

If these real-life examples sound familiar, you may have a caustic commentary running in your head, too. Psychologists say many of their patients are plagued by a harsh Inner Critic -- including some extremely successful people who think it's the secret to their success.

Humans have only three ways of expressing concepts in their minds.

As Twitter surges toward an estimated 12 million registered users by year’s end, some of us are starting to deal with what we recently dubbed “followholism.” You’ve followed so many people, it’s hard to keep up, and it’s probably time to do a little housekeeping.
