Which social bookmarking site do you prefer to use?

My students research, highlight, comment with Diigo. I highlight and comment on their wiki writing for feedback. Love having student accounts with education edition.

Just started using Diigo. So far using it to gather resources for my classes. I'll be showing to other teachers for their use for next year. I've also collaborated with former coworkers at another school for things they're trying to do with assistive technology and asked for any resources I had there.

Haven't really got into social bookmarking in a big way, I prefer the look of delicious but diigo has a lot of useful features, in particular groups, which are great for study and the ability to twitter bookmarks.

Personally I find diigo comments on pages annoying. i wish there was an option to only see them from your friends or fellow group members.

I use Diigo and Delicious. I have my Diigo Account set so that anything I post in Diigo also posts to Delicious. I love all of the annotation tools in Diigo, but I can find my bookmarks easier in Delicious. So I don't plan on giving either one up.

I use both: I post to Diigo and it cross-posts to delicious. Usually when I refer to my own saved bookmarks I pull them up on Delicious. I'm not currently doing a lot with groups and the highlighting functionality of Diigo. I'm very glad it supports cross-posting. I like and prefer the simplicity of Delicious, but there is a lot more you can do annotating-wise with Diigo so I am still sticking with it. I was delighted to learn about the "Diigolet" button awhile back that lets me post to Diigo from Safari as well. When I'm using the Firefox browser I post using the Diigo toolbar.

Diigo - because of diigo toolbar and groups. It's easy to live in diigo as well because it pushes bookmarks into delicious. Also I rarely need to log into diigo because of the sidebar tool in Firefox allows for easy searching. I especially love the auto tag recommendations!

I use Diigo exclusively and push to Delicious. Diigo had a stronger organization ability with more coming in version 3.5. Groups, lists, webslides, Firefox integration and others are reasons to explore it.

Whatever I put in diigo is set to go into my delicious account. I'd rather highlight and tag the web, but my homepage at home on one of my browsers is delicious because I like the featured sites that are just gaining popularity. It makes for great professional reading.

I also like simplybox - its a plug in that allows you to "clip" parts of web pages, put them in a box, comment on those pages or clippings, and share the boxes with others. Going to get my students using it next year.
