Pros
The Wikistrat Web 2.0 open-source platform is a truly cutting-edge concept and offers analysis product provided by an educated, diverse, and (generally) select community. Being a part of it offers great experience through training and occasional networking opportunities, especially for those starting out in intelligence analysis or more senior professionals looking to build a consulting business. Simulations are fantastic opportunities in both analysis techniques (it's a structured process), client services (you interact directly with the client throughout the sims) and thought leadership (the model is a novel concept).
Cons
Sometimes analysts are hired who lack serious analytical skills or experience and they muddle through and devalue projects. But they at least generally stand out and are eventually weeded out, as in any company. It's not hard to be recognized for contributions within the company but it's very difficult to gain recognition in the company's public face (senior analysts generally get the credit).
