Twitter has quickly become the must-have channel for conference back-chat. Reading what other people tweet during a speech provides an extra dimension as you get a sense of what the audience is thinking. And just like passing notes in class, it’s also a lot more fun than simply sitting and listening. (remember that Facebook interview from SXSW’08?)

Twitter is also a great way to attend a conference without actually being there – just follow a conference hashtag (e.g. #smib09 or #figarodigital) and find out all the gossip and the key points from the comfort of your desk.

But watch out Twitter. Google Wave is going to take this digitally-enabled conference back-channel a step further.

At the recent Ecomm conference delegates were provided with Google Wave accounts. What resulted was a fantastic showcase of collaboration and crowd-sourcing. Sprinkeled with a good dose of integrated offline and online real-time social media.
