The Conversation Engine (formerly Conversation Finder) attempts to find "conversations" between websites: directed graphs that (hopefully) indicate an ongoing conversation between those sites. This is of course useful mostly on weblogs, but it should work for other sites.

For more on the origins of the Conversation Engine, check out this post in my weblog.

New in version 0.2: The Conversation Engine is now using Feedster's API to target the search and provide context to the conversation through the metadata provided by the RSS feeds, and Feedster's information (such as photos).

Try it!

Enter two urls to find conversations between them. Since only a handful of sites are being spidered at the moment, please be sure to check the list of sites that the conversation engine currently knows about.
