One of the latest applications of Twitter #hashtags is to use them at a conference or professional development session to display people's tweets about the conference. I came across Alan Levine's (who blogs as CogDogBlog) discussion of how to do this. (By the way, Alan is the one who presented his dogs using many different Web 2.0 tools. I think Lori/Gloria mentioned him.) This discussion is from 2007 so I'm sure there are other ways to do this now. I thought I would include this here as a starting point for those who want to set this up for your next conference.
The discussion by Alan is quite technical but I know some of you are up for that. Check it out at 3 graphics + 1 XML edit: Skin your twittercamp. I wonder whether you would need a moderator to vet those tweets before they are posted?
I could see this working well for a PD including teachers who would love to interact with the speaker, to ask questions and make comments. In a similar way to our Eluminate session last night with Mack Male, questions could be asked and answered very quickly.
If this were to be used in a PD session, I think the speaker would need to have a clear agenda. Otherwise the presentation could veer off into answering the participants' questions rather than giving the talk with new information. For the presenter, there would be a fine line between interacting with the audience and presenting the information which is the reason why you were invited to speak in the first place.
