Cadmus is a real time filtering service that manages your stream (Twitter, FriendFeed and RSS) by displaying the most relevant content since the last time you checked in. It helps you get caught up on what you have missed. The problem we are trying to solve here is that we don’t have all day to stay on top of these social media services. Most people check into these services ever so frequently. And every time they do, they have to scroll through pages of posts to find out what’s going on. From the statistics that we have collected so far, we have found that nearly 20% of all the posts in a user’s stream are similar. This means that every time you login, you have to scroll through pages of posts with low signal to noise ratios. Cadmus fixes this problem by filtering out the similar posts and finding the relevant ones since your last login. This way you won’t feel like you are missing out on what your friends are talking about.
