If someone stops returning your texts, tweets and emails this weekend - he or she might not be blowing you off. The person might just be blowing off technology for a little while.
A pretty grand experiment was underway Friday night, called the "National Day of Unplugging."
Could you give up your phone, tablet or computer for 24 hours? The Day of Unplugging runs from sundown Friday night to sundown Saturday night.
The challenge was started by a Jewish organization called the "Reboot Network." The time period for disconnecting from electronics matches the traditional Jewish Sabbath - a day of rest and reflection.
The Reboot Network said its goal is to get people to reflect on our use of technology and to think about things we might be missing when all our attention is on our digital devices.
Local groups throughout the country are holding events for National Unplugging Day. About 1,200 people showed up at an "unplugging" party in San Francisco Friday night. All attendees were required to check their phones at the door.
Before sundown, people from across the country and world went on the National Day of Unplugging website to post photos of themselves with signs that read "I unplug to ___" and then the fill in the blank with their own response.
We found some locals on the site too:
Arianna Huffington got paid $315 million when she sold her website, The Huffington Post.
She's unplugging "to course-correct and remember what I'm grateful for."
