I feel like a curmudgeon saying this, but this doesn't strike me as adding any value beyond eye candy.
At least most infoporn (eg, http://beta.twittervision.com/) has some redeeming qualities of presenting the information in a way that provides some insight.
I think it has value within the context of a conference. As I mention on another comment, we used it at Be2camp north and it gave a dynamic, bigger feel to the conference. Basically, if you're going to have a twitter-fall type of display in your event, use this instead. Yes, it's eye-candy, but in the context of an event that you want to animate, eye-candy is very useful.
We had this at Be2Camp north last week.. it felt much more dynamic and lively than any of the other twitter visualisations I've seen so far. Thought that people here might want to be aware of it, particularly if you organise events with a twitter backchannel display.
Here's a currently trending term to see what it looks like when there are a lot of tweets on a topic:
Ok, my fault for not being clear then. I was referring to visualisations of tweets within the context of a conference (often, people use Twitterfall or just plain old search.twitter.com). Projecting Visible Tweets on the wall makes for a cool, dynamic feel, by comparison.
I know Twitter is desparately cool and widely used. But It seems fairly rubbish as a primary back-channel.
It's nice to be able to vaccum up tweets going out of the conference and not directly meant for people in the session/conference. But for direct feedback there are several chat alternatives which would be better, including IRC.

I don't see any here.
