about onetag
Onetag is a site which lets you track and display content about a specific event, conference or show. If you're a conference organiser, you can use it to display a real-time overview of the blogs, Tweets and pictures which are being contributed to your event. If you're attending, you get to track what everyone else is saying and to contribute to the buzz yourself.
It's simple to set up: you just tell Onetag the blogs, twitterers and photographers you'd like following, and which keywords or tags you want to track. The site then pulls all that content into one place and provides you with a variety of ways of displaying, distributing or consuming it.
