What if you added on 50, even 100 authors (not sure if there is a limit), then gave them all a topic to write about and post about in one day. It would be like those "Day in the Life of..." books where photographers have been sent out on the same day to photograph what they've seen. If posted all on one day, all postings would have equal weight, accessible by the labels given them. They could appear hour-by-hour, one on top of one another, filed by time zone.
It also brings to mind the spontaneous writing group I used to belong to. We met every week and wrote about whatever topic came up, suggested by books or participants. It could be an electronic/universal spontaneous writing get-together.
I'm thinking this is where I should go with the Places I have lived blog I have tried to start.(So far, every writer I've invited to contribute is too busy to post something because of their busyness at the end of the academic year). Maybe it wouldn't be always limited to places we have lived--one project could be about our present neighborhoods, right now, whatever particular hour the writer sits down to write about it; another day/project could be memories of a place and time... It could be an annual event. (Maybe more frequent if not so many contributors for people to read through).
I wonder if there is a way that I can do this where I'm not out spending all the time I should be writing (and marketing my own writing) on rounding up writers, editing and promoting another project that isn't all mine. I'll need to find collaborators who can help steer it along.
Has anyone already done a blogging project like this? I'll look around and report back.
