Gowalla is a really interesting App for the iPhone that can help you meet up with other moms (or friends!) and it’s free.  Often used in conjunction with facebook, or twitter, but great just on it’s own, Gowalla encourages you to “Check in” places that you visit.  When you do this, it lets your friends who also have the Gowalla App know.  A message gets sent to their phone (like a text message – but not counting as one, for those of you who don’t have unlimited texting, like me!).  I think this has some pretty cool possibilities!

Tell your friends where you are!

If you were at the Library the Playground, or out for a bite, you could check in at that location (create the location if it’s not already listed).  You can even add a description of what you are doing.  Your message would go out to your friends, and if they were near by, they could stop in.  It’s fun – and free, and might get you some unexpected playdates.  Gowalla works on the iPhone, Android, and Blackberry.  FYI, if you have heard of foursquare – this is pretty similar, but I think it has a few features that make it better.
