Is there a WhosHere-style (location-based) social networking chat app for Android? I like the WhosHere app for Apple iPhone iOS. Is there a similar social networking/chat app that uses location / gps to find people to chat or network with for Android? 

Here's some more info on the application: http://itunes.apple.com/us/app/whoshere/id284973016
Here's what I could find so far:

I'm Here Plus allows you to use SMS text messaging to check the status and GPS location of any person on your contact list, as long as they have "Im Here Plus" installed as well. You may also choose to send others your current location via SMS, whether with just your GPS address or with an edited personalized location.
If you root your android phone and enable wifi tethering, you could use your ipod touch tethered through the droid and still use whosHere


I haven't tested any of these out. If you can comment with which of these you prefer, that would be great! thanks!
