Cross Site Lookup - Goodbye!
In SharePoint 2007, for us to have a common metadata across multiple sites, we used to hunt down the Cross Site Lookup Component. We can bid goodbye now for the same. SharePoint 2010's Enterprise Metadata is the perfect answer for the same. You can just have the complete hierarchy appearing for you as a column (with intellisense) in any document library or you can just have one group selected there. For example, you could have Hardware Servers Desktops Laptops Software OS Applications Mobile as two sets. In a document library you could have terms appearing from either of these or you could have just a term appearing from one category! Cool, try it out.
