A lot of folks are mashing up Twitter to come up with interesting sub services and some neat visualizations.As more people join and more people are. And as more people spend more time on the service, it's becoming more and more useful for marketers to look for insight in what is said on just Twitter, itself. You might expect marketers to discount the bias or inside-baseball quality of Twitter but not so. I know one marketer who made a very persuasive argument about revenue missed from just negative mentions on Twitter alone. New visualizations are springing up every day and offering intersting views of what people are talking about. Here's three:
TwitterThoughts is a cool interactive chart that not only plots topics over a period of time but will actually show you an animated timeline of keyword topics.
TweetVolume lets you input about 5 keywords to see overall volume of Tweet mentions. It's not clear over what period of time the data spans but it still is interesting in that simple Blogpulse kinda way.
TwitterFountain mashes up tweets and Flickr images and is billed as a neat way to add dimension to event coverage. The next time you go to a conference - WOMM U 2009, let's say - participants upload and tag images and tweets are overlaid via hashtags.
