The most promising Web 2.0 Software of 2006

Category : Personal Productivity and Organization

Category : Search

Best New Offering : Google Desktop Search 3.0

Although privacy concerns abound, Google's latest version of its Desktop product is slicker and more powerful than ever. And it even offers the eyebrow-raising feature of keeping a copy of the search index of your local hard drive on Google's servers so it can be accessed from anywhere. While other search engines are increasingly moving to social capabilities, Google instead raises the bar on raw features.

Category : Video Storage, Sharing and Search

Best New Offering : Stickam

Video is finally making a splash on the Web and though big players like YouTube have virtual domination of the space, new players continue to enter and Stickam is one of the more interesting new entires. Billing itself as an easy to use multimedia tool that "does it all", Stickam allows users to host all sorts of media including podcasts and video on their blog or website. It even supports uploading of media from mobile phones.

Category : Real Estate

Best New Offering : Zillow

The real estate business has been one of the very last traditional brick-and-mortar businesses to fall prey to customer self-service on the Web. Zillow is helping change that and despite criticism for certain quarters, it's actually a pretty compelling application. Zillow gives home buyers and sellers with tools to get estimates of home values and to compare it with similar offerings in the area. Loaded up with deep pockets, if Zillow can just continue to improve the accuracy of its data, it'll be a huge hit.

Category : Music

Best Offering : Podbop

One of the more innovative music applications to come out this year, Podbop has a visceral appeal that is immediate. A mashup of several underlying services including eventful, Podbop allows users to type in their city and state, listen to bands coming to the area and if they like them, then arrange to go actually attend a concert to listen to them. Sporting over 1,500 bands, Podbop works well, is fast, and seems to have a very appealing mix of music.
