It was just the other day when I mentioned that we need a visual way to see what topics people Twitter about, something like tracking popular keywords, the word burst type of thing.
Well this has been answered by delving into the Twitterverse, see the word bursts for the day or yesterday in the cloud.
Track the Twitterverse throughout the day to see how topics change over the day, or how their impact lessen or grow.
They also have archived search, like I menioned before I’d like to track keywords like I track people, whether via a search feed, or actually tracking keyword updates by SMS in Twitter itself.
Keep abreast of things to come at the Twitterverse blog.
