Consider this: while I am a long time wiki user, when presented with an empty space I still waste quite a lot of time in getting a space to the right structure. Adding MeetingNotes pages, adding templates, experimenting, fighting with macros etc. My work and productivity would have been ten-fold better had I been able to select from a space gallery that Atlasian or people in a similar setting have created and posted. I can practicly hit the ground running. This should be a tremendous sales booster. I am currently evaluating this product and am working hard with an extremely tight schedule to get the management to buy in (other options being evaluated include Jot and SharePoint). Such a feature would have made a difference.
