"Hey H., you know what would be awesome? A service where you could register a group of friends' phone numbers, then when you're out and about, you text your location to a server and your friends could text the server and find out where all their friends are."
"You mean like Dodgeball?"
I search for "Dodgeball text" and find out that not only has someone already thought of this, but Google has bought them already.
All the same, someone needs to launch this in Ireland. It would make weekends so much easier to organise. I hope this is built into Live Anywhere.
