Yenta can figure out what you're interested in. You don't have to tell Yenta what you're interested in. If you talk about it online, or write files about it, or can even grab copies of files other people have written, Yenta can determine your interests.
Yenta knows you have many interests. It tracks each interest separately. Interests may come and go, and Yenta will notice. You don't have to keep updating Yenta by hand.
You can send messages to people who share one of your interests. You can send a message to just one person, or to an entire group of people who share one of your interests. Yenta keeps track of your conversations, so you can go back to them later.
Yenta can introduce you to others. If Yenta finds someone else who looks like an especially good match, it can suggest an introduction. This might encourage you to talk to someone else whom you hadn't known before.
Yenta has a built-in reputation system. You can use this system to help you decide whether or not to talk to a person, or how much to tell them while you're getting to know them.
You can filter out messages you don't want to see. You can do this on the basis of someone's particular identity. You can also use the reputation system to filter any message, even from people you haven't met yet, that don't meet your criteria. Spammers can't operate in this environment.
Yenta protects your privacy. Yenta never tells someone your real name -- in fact, it doesn't even know it. It doesn't store all of its information in one place, so neither crackers with computers, nor lawyers with subpoenas, have a single place to attack. And it uses strong cryptography everywhere.
