While some of the aggregate information that can be gleaned form twitter is interesting, I have yet to see anything approaching a single meaningful message.

I know that many people seem to like twitter, but every time I go to the twitter website I leave without experiencing anything interesting. Maybe I'm doing it wrong.

I use Twitter extensively, but I can't say I've gone to the actual Twitter website more than a dozen times. I think the most interesting uses of Twitter involve using Twitter data in other places, like putting a stream on your blog. I think that's where the future of Twitter is. I saw a cool Twitter/Flickr mashup a while back that took a Twitter stream and translated it into pictures, which was cool.

Cool service - I just tried it out on my account. I'm not really sure if I see a huge increase in relevance, although that might be because I follow a lot of random accounts vs. people I actually know. Feedback: I don't like that it's a blackbox and I can't scale/finetune things to adjust the filter. What gets filtered out should be transparent if you want people to rely on that service.

Also you have to define noise, and why are you getting it anyway?
