Lissn is a service that launched at the TechCrunch50 conference. Lissn is basically a fancy chat room. Lissn is a service that starts with someone starting a conversation. Anyone can join the conversation thread and the administrator can select whether contributors can publish their comments. On the homepage is the most popular Lissn conversations. Conversations are automatically converted to your language of preference using Google Translate APIs.
Contextual advertising appears as conversations are made. For example, if you are talking about a specific book, an ad will show where to buy the book on Amazon.com. This is how Lissn would make money. You can find out what conversations are taking place near you using the IP address detection.
Lissn launched this month and was founded by Myke Armstrong.
