Hi Mira,
Edd Bagenal here, i have also been using Delicious to save bookmarks both for my own work and as part of the Computing and Interaction Design BA that I have recently been employed to lead. I have added our networks to one another and had a look at your bookmarks also. Some great stuff.
I'm attempting to pool research for the various briefs that the students are working on and I'd be interested to hear any ways in which you have been able to use and share delicious resources within a research group.
Cheers,
Edd
