Foursquare: Yet another social-networking service I'm the last one to know about...

The world is becoming more stalker-friendly.

At least that's the first thing that I think of whenever someone explains this up-and-coming social-networking outlet to me.

Foursquare is a smart phone app that allows you to 'check-in' at certain public locations and post reviews and tips about that hotspot for all of your friends to see.

I really don't think, as an individual, I could ever see myself using this. It's just plain creepy. However, I was at a meeting where a woman from Seattle Weekly was discussing using the service under the name of an organization in order to promote events and the businesses of local partners/neighbors, and that's pretty brilliant.

While Foursquare may not be the most familiar of the social networking giants, 41 percent of its traffic comes directly from Facebook (500 million users) and Twitter (100 million users) as users share check-ins (That Agency via Hitwise), and that's a statistic to take notice of.
