Do you know of someone who spends entirely too much time plugged into their Blackberry? Does their idea of true social interaction usually involve spending quantity time on social media sites like Facebook or Twitter?

Would you like to let your plugged in friend know that you’re concerned about them? Well now you can, thanks to the folks who bring you Meetup.com, a social networking portal that facilities in-person group meetings.

Recently, the Meetup team launched a new website, unplugyourfriends.com, which allows you to send a friend or loved one a prepackaged “intervention email” and an invitation to view an animated video that cleverly illustrates the perils of tech addiction.

The sponsors say they are responding to an epidemic they call “Screen Addiction,” in which “the electronic screens invade every corner of your life.”

Selecting from a dropdown menu, you can customize your missive — telling your tech-obsessed friends that you “care” or, alternatively, that their habit is “getting annoying” or that you “know what it’s like.” Other customization features let you express fear that your email recipient risks turning into a zombie or may soon forget how to say words out loud. You can even ask your plugged-in friends to think about when they last saw the sun, laughed out loud instead of LOL’d, or did something that didn’t involve a screen.

We think the concept behind unplugafriend.com is a great idea. If you’re worried that someone you know is a little too wired to technology, why not deliver a tech intervention today?
