I am still surprised how few conference organisers have really caught on to social media and have learnt how to use it effectively. So much can be done with social media to help market an event and make it more participatory and engaging but one of the simplest things is to agree and communicate a conference tag as early as possible.
At KM India recently tweeters had to guess the tag which resulted in two tags being used #KMIndia and #KMSummit which resulted in a lot of confusion.
This great post on Tagging and face-to-face events by John David Smith makes the case for conference tags and gives some solid tips.
