The good news is that diigo.com is not defunct.
The bad news is that their domain has been momentarily hijacked, see http://www.diigo.net/about/domain:
Dear Diigo users,
We’re terribly sorry to inform you that we’re experiencing domain hijacking, ie. someone gained access to our Yahoo domain registrar account, and illegally hijacked the domain, www.diigo.com. Very soon www.diigo.com may not be accessible to you until this issue is resolved.
But please rest assured that all our servers and user data are NOT compromised, and your data can be alternatively accessed at
www.diigo.net
Your current Diigo extensions and bookmarklets will not work on diigo.net.
