Here’s a Buzzshout review I wrote on Central Desktop. This company’s views on collaboration software, email, and the future are extremely valid. Their product was adopted company wide at my 20 person software firm within 5 days…without "feature whine". We bypassed IT entirely since they wanted another 2 developers, $150k, and 18 months to deploy sharepoint fully. Fuggetaboutit.
The company’s co-founder wrote a salient piece that appears on the Central Desktop Blog. This piece has been "mega-linked too" and is a very clear piece of thinking that seems to be a hallmark of many of today’s Web 2.0 firms. A MUST READ.
