Some of this will be old hat to some of you, but I've just finished running our regular 'What can you learn in 15 minutes' day - this one about Web 2.0.
It's a pretty simple format. Get 10 or so presenters, and ask them to talk about one thing for 10 minutes - it's kind of like the 'Pecha Kucha' concept, only because we're actually trying to teach rather than just perform, we don't make people use PowerPoint, and we don't make them auto forward their slides.
The aim is more to inspire and inform than to teach, but there's a whole heap of penumbra stuff going on as well to do with promoting ourselves as a service.
Anyway, today we were streaming the presentations live, so people who couldn't make it to the hall could watch them. As well as the committee of the conference I gave a paper to last year on running sessions like this, there were several of the people in the Library school here watching too. As one of our presenters was talking about Twitter, I thought that I really should Tweet something about it. So I took a photo, uploaded it, and gave it the #ucl hashtag.
When I searched for the hashtag, I found the tweets that the library school were publishing. So I started talking to them, answering questions, getting feedback from the people on the live feed and passing it to the presenters. It _really_ opened up the day for me - put another layer of value onto what we were doing.
And while I was watching one of the presentations, I was sorting out a meeting with the people from the library school about running a similar sort of day but with much wider participation from academics across the University.
So - twitter - not just for twits!
