Foxed by Foxmarks

Mitch Kapor, he of software archaeology fame, has started a project called Foxmarks. According to the FAQ:

Foxmarks is an extension for Firefox that allows you to synchronize your bookmarks across multiple computers. Install Foxmarks on each machine that you want to keep synchronized, and Foxmarks will automatically propagate bookmarks changes that you make on one machine to all the others.

Hm: isn't this what Google Browser Sync does? And then some:

Google Browser Sync for Firefox is an extension that continuously synchronizes your browser settings – including bookmarks, history, persistent cookies, and saved passwords – across your computers. It also allows you to restore open tabs and windows across different machines and browser sessions.

But wait, Mitch says there's more:

I’m incubating a new startup, which is pretty exciting because we’re working on innovation at the intersection of search and social production. Think of new services which are a cross between Google and the Wikipedia.

BTW, Mitch, how is Chandler coming along? (Via C|net.)
