Alright, I embrace social networking all the way

But even I don't get why any prudent person would want to broadcast their coordinates to web sites such as Foursquare, Twitter, or Facebook. It just seems, well, stupid to do so.
Facebook launches Places location based service

Social networking behemoth Facebook has added a feature that allows members to share where they are while on the move.

Places, as it is known, marks the company's first foray into the "location-based services" space, which has become popular with users who want to share where they shop, eat or play.

Sites such as Foursquare and Gowalla already offer similar features.

Places will initially only be available in the US through Facebook's iPhone app or by logging onto its smartphone site.

The company plans to extend the feature to all its 500 million members as soon as it can.

"This is meaningful because you can stay connected with your friends around you," said company founder Mark Zuckerberg.
