Mark-Kashman,
My client has been holding off building a project management site collection and I think the timing with Hubs/General Release is going to be perfect. Some existing SharePoint Team Collaboration sites (not Team sites) are managing documents that we'd want to connect to in a possible project hub, and ultimately archive completed project documentation from the hub into those existing Project Management documentation sites, on project completion. How friendly is search from Hub with regard to pulling content from another site collection? CQWPs are....ok....but it would be nice to not have to build them in the Hub to surface the Collab Team documents.
A sort-of related comment: Please can MS blog commenting settings display the most recent activity first, rather than making readers have to toggle through to the end page to add an item? Maybe add a Search Comments feature, like in User Voice, so we can see if a comment has already been made and what its replies might be. Thanks -
