I have a general architecture based question (out of curiosity, not to judge, to challenge decisions made by the SO team) about Stack Overflow and similarly architected sites...
Of all the selling points* of Windows Communication Foundation as great for SOA, is Stack Overflow simple enough (not in a bad way) to justify not needing to use WCF? I'm asking to help build guideline for myself on when using WCF makes sense.
Or would the lack of a need for WCF also stem from the "speed as a feature" of Stack Overflow where "another layer" would just be slower.
*Selling points such as; unified model, various security benefits, reliability/transactional, App Fabric integration, etc
Updated question to reflect desire to determine guidelines for choosing WCF, and when it's an unnecessary layer.
