Location based social networks are becoming all the rage! From #SXSWi’s #foursquare vs. GoWalla geo-wars to the neon billboards on the Vegas strip of who has checked in, it is obvious this is the way of the future. But are you worried that people know where you are?

When it comes to social media, there are two kinds of people:

1) Smores like me. These are social media whores. Folks who love to network and don’t mind the issue of privacy. I love community and engage in it often.

2) Reserved networkers. These are the folks that use networks to only engage with folks they know offline. They tend to respect privacy, want heavy filters and do not want to let folks know where they are as.

Good news for both! There are new apps out there!

For those that want to only let folks they personally know what they are up to and keep that information locked down to a small group, well then Rally Up is for you! My good friends over at @12Seconds combined with other have made this awesome app! I have mad respect for the crew over there, so download it and give it a try. You will not be let down! Oh, and bonus: go to their page for a chance to win an iPad!

For those that want to broadcast it to all and have several networks to do so (Brightkite, FourSquare, GoWalla, Causecast, Latitude, etc.) then Check.in is one place to do that to all networks! Currently it is in closed beta. I have access. Either sign up and wait your code, or hit me up for access. You know where to find me!
