No one with any tact would ever tell you that you look fat to your face. But a sea of anonymous netizens will tell you in real-time on multiple channels. Kim Kardashian, Beyonce and Twilight's Stephenie Meyer all come up on real time search engines if you type in "looks fat". And each of these women would see these painful comments if they listened to the publicist who told them to "measure brand conversation". When we last covered UberVU, the company had just launched ContextVoice API - an API that helps developers create tools for conversation tracking. Today, the company added new search functionality to ContextVoice with a number of useful filtering options.

When PR agencies encourage corporate executives to engage in public dialogue, they tell them to "embrace the chaos". As of today, chaos has a measurement API, and its name is ContextVoice. Romanian SeedCamp winner UberVU just launched ContextVoice in the hopes that inquisitive companies will "track the web's conversational graph". In other words, we're about to see a smorgasbord of brand commentary and all the social media trimmings will be there.

Recently people have been comparing lifestreaming services FriendFeed and Socialthing!, trying to determine which one will win or whether they even compete. For example, see ReadWriteWeb's post FriendFeed vs SocialThing!. I signed up for FriendFeed when it first came out and more recently I was lucky enough to get a private beta invite for Socialthing! as well. I sat down with Socialthing! founder and CEO Matt Galligan, to get a little insight into the differences and similarities between the two products.

Here are some of the highlights from the week's Web Tech action on ReadWriteWeb. This week includes social networks and lifestreaming analysis (Facebook, FeedFriend and more), a look at new Semantic Apps, and a new service from Amazon.
