While at Sharepoint Saturday I attended an interesting session titled, "Workflow Visio and SharePoint Designer". I was really amazed that WF had finally found a home in Visio. Visio is a great designer tool for modeling applications through flowcharts and now business users like business analysts and 'subject matter experts' are one step closer to actually being able to design workflows and have them pushed up to Sharepoint. One of WF's greatest features is giving business  professionals the power of designing workflows so that developers do not have to.
