I really, really like how you implemented this. Totally unobtrusive. The small delay while the diigo results are displayed is noticeable, but not at all an issue I think. The number display is enough to know if I want to jump to Diigo to get results. I think it is an awesome touch to add a link to the settings dialog right on the page. Overall great work.
If I had to suggest a feature I would suggest trying to actually match results in Google to results in Diigo and somehow denote that a particular link on Google has already been saved. The ability to save to Diigo directly fromGoogle might be useful as well, especially for read later things.
