what to keep private.

when you lose connections to Diigo servers, either because you lost internet
connections or because our servers are down. Unique to Diigo!

We're often asked how our service compares with the traditional way of
bookmarking, and differs from other social bookmarking sites, such as
del.icio.us. Well, of course, the most obvious is that only Diigo provides the
web highlight / annotation service. In addition, there are many other important
features and details that set us apart. (We, and some of users, believe that
Diigo is almost certainly the best online bookmarking and annotation service out
there. We hope you agree with us, too.) As one user puts it, "Diigo, I'm calling
it - del.icio.us with brains"!

Here is a simple comparison chart that lists some of the differences.
