Thanks for posting that link. I live in Wisconsin and it saddens me to think that the only bookstore that will survive here is Barnes & Noble. I think that the closure of stores in smaller towns illustrates the increasing isolation of people due to technology. People will have to depend on public libraries for the type of community events you describe, but their situation is precarious due to government funding cuts.
Although I still spend time in bookstores - sometimes hours perusing what's out there, I don't spend as much time or money in them as I used to. It's easier to read my books on a Kindle or buy the books online so I don't have to lug them home. It is really sad that the bookstores are going the way of department stores and that most people are buying online.
Working for the airlines, I do notice that passengers still have real books to read during flight and that the airport bookstores seem to be as busy as always.
