The Time When is a trial website in development for the BBC; it is a place to record and share memories of the important days in your life. The idea is that it might build, in the long run, into a collection of eyewitness accounts of historical events.
Rather than immediately develop a full, polished product, the team are piloting the idea to see what works; public betas are quite a novel approach 'round these parts. Not content with being clueful enough to develop a nice, lightweight prototype, the team (well, mostly a chap called Phil) have also made 40,000 new RSS feeds available.
There are feeds for all of the memories added to the site, feeds for individual users, feeds for their friends and most interestingly, feeds for each day from 1900 to today.
So, please - add your memories, test the site, and think of excellent things to do with the feeds. What other sources of time-sequenced information could you mix in with memories? What about visualising memories in Simile Timeline? Could you cross match memories with places?
