To see them in the context of the conference programme, I converted the tweets and the event schedule to XML suitable for display in a Simile Timeline. Click the screenshot below to access the resulting timeline mashup (nb tweets take a few seconds to load).

What would have made this exercise easier, and the conference tweets easier to track:

• If the conference programme had been published in a more mashable format eg iCal / XML
• If there was a way to identify a particular conference track (a sub hashtag? – or is that overkill?)
• A way to distinguish critical comments, reportage, and general flim-flam. Though perhaps that is part of the fun!
