CoTweet: CoTweet's already the Twitter CRM Tool of Choice for BestBuy, JetBlue, and Ford, and that's because it adds a businesslayer to Twitter account management.
This closed model allows Velocity to provide a decoupled templating presentation layer, cleanly separated from any application business logic or data management code.
The client layer in this regard can refer to calls made from a Web framework, portal application, desktop system, or in some cases, a workflow product or business process management (BPM) component.
