In the past couple of days, I've been working on history. In accordance with my development program, I got as far as adding a new page on antiquity, the 3rd millennium BC, then decided that I was really not that much interested in antiquity, or late medieval times, or the 18th century. I switched to another approach I have been using, one of starting from the present and working backward.
Wikipedia is doing well at keeping an ongoing, up-to-date chronicle of events, which is something I have difficulty with. This allows me to keep almost up-to-date, something I have difficulty with when the only source of current events is daily news. The last 20 years is now split into 5-year pages, and I have a page for the current year and each of the last two.
I would like to narrow the gap between when events occur and interpretation of them, by being able to fit major current events into historical context as soon as possible. These new pages bring me a step closer to that goal.
