Pros
CBS and CBS Interactive really do focus on creating great quality content. While the tech, design, product and sales teams are treated very well and are key collaborators, CBS is different because of the quality content produced by the journalists at CNET, GameSpot and Chow. But CBS does not slack on innovation. Fantasy football on CBS Sports is well worth paying for even with so many free alternatives. Metacritic's ratings aggregation algorithm really helps to identify quality. And CBS has developed it's own ad serving and BI systems that rival DFP and Omniture but enable CBS to have much greater control over advertising and customer insights.
Cons
Change is a constant at CBS Interactive. Because the company is re-organized every 6 - 9 months, long term veterans of the company - and there are many with 10+ year tenures - are inured to shuffles. This means that all of the re-orgs create uncertainty in the short term, but affect minimal long term change.
