The Montague Bookmill, which Seth Godin says might be the "bookstore of the future."
In this vision, the bookstore becomes the center of an intellectual community. Much in the spirit of a English Coffee House in the early 1700's. As Ned Ward wrote around 1700:
"There was a rabble going hither and thither, reminding me of a swarm of rats in a ruinous cheese-store. Some came, others went; some were scribbling, others were talking; some were drinking (coffee), some smoking, and some arguing; the whole place stank of tobacco like the cabin of a barge. On the corner of a long table, close by the armchair, was lying a Bible..."
For the modern coffee house cum bookstore maybe add to the "rabble going hither and thither," high speed wireless access, and a large flat screen display with authors giving 'web seminars.' Or perhaps the flat screen will be showing TED or Fora.tv videos.
