Should Twitter replace Q&A?

More twitter talk... Jimmy Ray and I were brainstorming how we might be able to use Twitter when a show is streaming live to get a more animated (and transparent) conversation going about the topics on a given show. For every live show, we feature a Q&A with experts that is chat based via the on24 interface. We capture that Q&A and make it available to access if you are watching the replay. Why should some of that conversation stop? Could we not make it more valuable and long lasting if we moved it to Twitter? Couple of angles to consider with this:

1. Not everyone has twitter. (This once again highlights the viral networking nature of an app like this...’please join so we can add value to each other...’)
2. Twitters are limited to 140 characters. (pro and con - be concise with your question - we will have to be concise with our replies.
3. On the pro side - the conversation is viewable by all. More than just a designated group can get in on the conversation. Expands the value I believe.

I don’t quite have it straight in my head on how to do this - I think we will just start trying it over the next few shows. You can follow both me and Jimmy Ray on twitter. We have also created a TechWiseTV twitter account to follow for use during the shows.

I wonder hashtags might give us more creative options? Still a very emerging capability... so I don’t place this high on the urgent list... more about hashtag’s here:

From the about page on the Twitter Fan Wiki:

Hashtags are a community-driven convention for adding additional context and metadata to your tweets. They're like tags on Flickr, only added inline to your post. You create a hashtag simply by prefixing a word with a hash symbol: #hashtag.

Hashtags were developed as a means to create "groupings" on Twitter, without having to change the basic service. The hash symbol is a convention borrowed primarily from IRC channels, and later from Jaiku's channels.
