We are bombarded by digital communication. Email, chat, and instant messaging is quickly being joined by blogs, twitter, and social networking sites. Efforts is a project for proposing how to organize digital communication by topic, project, and person.
relevance: three levels of interaction
One of the considerations is how much the sender is meaning to interact with you. People are different, so the same type of communication might find itself at any level.

1. You should read and possibly respond.
2. You should at least skim.
3. It's just passive communication and is probably publicly accessible.
