I love Delicious, and I have begun to use it for work projects and collaborations in which a team of which I am part, must benchmark what other organizations are doing or gather information about our own organizations' program. For example we are benchmarking customer service within our organization and in other government organizations. Delicious makes if very easy to collect all relevant sites (PDFs and intranet pages) into relevant categories using tags.

I think Diigo is an awesome way to give feedback. We can choose to give feedback and share it publicly, with the ETC group or make it private. It enables us to post the sticky where it is most relevant in the site. It enables us to return to the group (ETC) and read the general comments on each unit. Very useful learning tool. On the downside it takes some practice. Stickies can disappear if you navigate away, which is disappointing if you began to type post and it is lost. Also there has been some confusion about where and how to post. Some of us (me included) at first posted my answer to Chih's questions in relation to another person's project; I deleted my posts in the wrong places and reposted in relation to my project.
