Google Latitude is out, giving your friends the ability to tell where you are (or at least where your mobile phone is) 24/7. You can, of course, opt out in whole or in part - updating your location manually, or concealing it altogether. Which should prevent certain awkward conversations ("If that's my mother, tell her I'm not here!")... but maybe at the expense of triggering others ("Exactly why weren't you on Latitude tonight while you were 'working late'?").

In this edition of the Weekly Wrapup, our newsletter summarising the top stories of the week, we continue our series on recommendation technologies with a special RWW Live podcast and a review of Baynote; we analyze a new Google product called Latitude, which could change the way you network on mobile phones; we describe how a Facebook "Sentiment Engine" could be huge; we look at the rise of the "goverati" in the new web-enabled U.S. government; and more. Also check out the highlights from our Enterprise Channel and Jobwire, ReadWriteWeb's new product which tracks hires in tech and new media.

Where you are is as important as what you're looking for. That's why more and more services are looking to location as a filter for providing relevant information when and where we need it. So it only makes sense that Google - a company known for its ability to deliver relevant information - get into the location-aware app game. Today, they jumped in with both feet by releasing Google Latitude, a way to keep track of your friends' current whereabouts - and let Google have a view into your nomadic or sedentary habits.
