Andy Baio's Upcoming.org is an interesting service (via Marc via Matt Haughey). No, there aren't any really new ideas there, but Upcoming is an implementation of ideas that were talked about before, something to grab and shake. Ray also found Upcoming interesting and asks some good questions.
Upcoming is, of course, related to the idea of enriching ubiquitous calendar on every blog. Events from Upcoming could be used to populate a blog's calendar as well as 'day' pages so one could see the events related to specific time period. Since most interesting events are those yet to happen, blog architecture and UI has to change. In the end, blog calendar turns into a calendar aggregator.
I am not happy with Upcoming UI though, but it's a start.
