Twingly is a search engine for blogs. Search is the most common tool for combatting information overflow, but we are also working on providing a personalized experience and tools emphazising discovery rather than search.
RSS readers provide updates for groups of blogs in a very streamlined fashion. Most readers use a form of interaction similar to how we read email, with an inbox and folders providing to organization and focus.
The problem of information overflow exists in both environments. As the volume of incoming messages climb, each message takes on less and less value to the user. The effort required to sift through the stream of information seems to be exponential to the number of unread messages.
RSS readers suffers from more irregular use than email clients. In periods of high activity, the user adds lots of blogs in order to always have something interesting to read. In a period of less activity this accumulates quickly into infobesity.
While email clients such as GMail group individual messages into conversations to combat information overflow, this has not been seen in RSS readers. Instead, memetrackers such as Techmeme.com and the Swedish Knuff.se has been very useful to provide an overview of what blogs are talking about.
Twingly will be able to provide you with the same overview of the conversations going on in the blogosphere, but based on a selection of blogs that you care about. You will always find anything interesting to read without the threat of being overrun by thousands of unread blog posts.
