Soylent intends to be a "people browser" that wraps every useful bit of information about people into single, cohesive objects. So your friends may have a dozen IM screen names, email addresses, website usernames, icons, hundreds or thousands of photos, and so on. Soylent is meant to bring all those types of communication and content together so you can perform and reach them within a few clicks.
