TechCrunch50 hit San Francisco this week with a number of big players announcing new products and features.

Facebook introduced its own version of Google Labs called Prototypes, a collection of experimental features, available as applications on the developer platform.

Google also had a new product to share at the conference —Fast Flip — designed to simulate the experience of flipping through traditional soft copy newspaper and magazine pages, while Microsoft unveiled a new Visual Search feature for Bing. Not exactly sure how useful either of them are. You be the judge.

A study by a company called uTest revealed that amongst the popular search engines Google had the least bugs, while Bing had the most.

.NET developers will now be able to build iPhone and iPod Touch apps with Novell’s new MonoTouch framework. The catch is it doesn’t come cheap. If Android is more your style, SDK 1.6 has been released.

The main competitor to Google Docs, Office Web Apps, has recently been released as a technical preview.

Also making news this week, Adobe announced plans to buy Omniture for $1.8 billion, while Google Maps finally got Aussie live traffic data.

Weekly articles featured tips on how to ace a phone interview, Linux file managers you should try, and .NET’s lambdas.

Chris Duckett blogged about Microsoft’s surprise initiative — the open source CodePlex foundation, and how IT certifications can get you a promotion.
