Your Twitter stream is being flooded by that tweet-happy friend who posts entirely too often for your tastes. They aren’t quite so annoying that it warrants an “unfollow”, but their updates definitely do soak up a bit of your feed and not always with stuff you want to see. Fortunately, there’s an app for that.

It’s called Shuush, a service that shrinks the font size of tweets from users who post too much down to absolute unreadability, then enlarges the updates from Twitter users who only post every so often.

Shuush is a prototype web based Twitter reader that ranks your followers on frequency of tweets. It aims to amplify the people that don’t usually get heard, and scale back those with frequent updates.

After logging into the Shuush website with my Twitter login, my dashboard reads, “Your Shuush level is 11.” What exactly does that mean? According to Shuush, this means that I post at the highest level of frequency on their measuring scale (oops). If you happen to be following me on Twitter, my tweets will be shrunken down on your Shuush dashboard so you don’t have to listen to my blabbering and can, instead, focus on tweets you might actually want to see.

Shuush measures your tweeting level frequency on a scale of 1 to 11 by how many tweets-per-day you’ve sent since joining Twitter. What level are you?

Twitter tools similar to the service include Echofon (it has a “mute” feature to silence the more active tweeters), and Proxlet, a Google Chrome extension designed to block apps, mute users, and filter hashtags directly on the Twitter website.
