An idea for use of Twitter/Jaiku...

I've been getting excited by the idea of giving students virtual work placements through Twitter and Jaiku: You ask a tradesperson or professional to keep a Twitter or jaiku throughout a day (or a few days). Students view these via the web or subscribe to it via their mobiles and can ask further questions (by commenting or replying). They can then add their own mini-reflections using the micro-blog or a full blog. This is supplemented by keeping up the Twitter or Jaiku when they go on work placement. Would love to see this happening and get case studies for this!
