Some time ago I posted thoughts about potential use of Twitter in cultural exhibits (and had some good conversations with Shelley Mannion about her very interesting work with the Tibetan teens in Switzerland). The ability to quickly compare experiences among cultural groups seemed promising.
I've continued to play with Twitter, and had an interesting experience this morning when I was in Harvard Square. I posted an entry about looking at sunlight on the bricks in Harvard Square. Within an hour, I received a notice that my postings were compiled ("followed") by another user, "Harvard Square Now!". And this seemed to be a compilation of all the postings containing "Harvard Square" in the text.
That kind of automatic compilation is pretty amazing. A shared experience in a public space. I'm thinking of implications for other major cultural venues, like Ellis Island, or the Holocaust Museum, where it's likely people will be posting about their experiences regularly...
