At a recent SharePoint conference (SharePoint Fest in Seattle) there were at least two speakers who advocated in limiting the number of subsites used. Rather, they suggested creating Site Collections for any logical separation of business (e.g. Unit, Department, Project) and then deal with the navigation of the flat hierarchy elsewhere. My question is twofold:
- Is this actually a widely recommended approach?
- If yes, what have you done to handle navigation around and between Site Collections?
