Hmm Did Diigo change their browser search plugin? You know the opensearch plugin that works in IE7 and Firefox

It used to search both diigo bookmarks and Google, but now it searches only diigo?

Qitera has a very nice feature. It's toolbar intergretes with Yahoo, Google, MSN, when you search any term it will show results from the social bookmarking tool as well (shown seperately)!

Killer feature! Try it and you will see what i mean.

That plus Qitera/iterasi's ability to cache any webpage (even password protected sites) are the only two features that Diigo lacks compared to the rest.

EDIT Scratch that. I see there is a searchplugin for Google + Diigo that does something similar. Very good, so i guess there's just one thing that Diigo is weak in... Caching..
