This is a cool idea based on an app made by Jeff Weinstein and Steve Pike. The idea is that even though you know that your Mom worries about where you are and if you got to your destination safely, it is not cool calling or sending her an SMS.
However, with #mom it is easy, you use it in conjunction with a Foursquare account, so add #mom at any check in and she will get an automated message either by call or sms, simple!
Here is what the crew over at hashtagmom.com have to say about this cool idea;
Today, we’re launching a new service called #mom that makes it easy and fun to let mom know where you are.
1. Sign up at hashtagmom.com
2. Add #mom to your Foursquare check in
3. She gets an automated call or text
