Simply delicious
I'm a relatively new user of Delicious, despite signing up some time ago, I only actually started to use it regularly in October last year. Since then I've become addicted to it. It's been almost a year since I bookmarked anything on a local machine and it's proven useful on a number of occasions when showing people things. My future wife and I have even worked out our own tagging system so we can bookmark things for our wedding and easily find things relating to it on each others bookmarks.
Now onto what I was writing this for in the first place. I hardly ever scour Delicious for things to read, I simply don't have time, so when I open up the site, I head straight for the network section. I now follow many people who provide me with information, resources and inspiration on a daily basis. If you've never used Delicious and want to but don't know where to start, I've put together a short list of people in the web community who may bookmark pages and sites that are of similar interest to you.
If you like your breakfast with a dash design inspiration Harry Roberts, Colly, Jason Santa Maria and David DeSandro are great people to add to your network, posting not just inspiring site designs but also plenty of informative resources relating to typography, grid design and much more.
For an added dose of design related bookmarks with Web Standards and more tech stuff mixed in, I suggest you head over to see Si Jobling, Dan Donald and Jasper Tandy. They'll supply you with a nutritious diet of web design and development resources.
That'll do for now I think. Even if this is a starting point for you, the best thing to do is just play with it yourself, find your feet and add people to your network organically. That way you'll get a feel for what certain people bookmark but you'll also not be overwhelmed with hundreds of bookmarks to sift through, which would undoubtedly happen if you added 20 users at once.
