My current favourite blog.fiction is Today in Alternate History - Important events in history that never occurred today - so go read. Each paragraph is so potent, each just wanting to expand into a whole continuum.

From there I followed a link to This Day in Alternate History, which I guess is the same site in a parallel universe. Actually, it's completely different, collaborative, and stuffed full of timelines. You can read all the various timeline events for today's date. Now how about a syndication feed for this, or an iCal calendar? (The spec's not too hard - just text - and if you stick to vCalendar version 1.0 and avoid the 'duration' field, it'll import into Outlook too.)
