delicious like sites

I surfed to site that had a bunch, 20, mybe icons with links to sites like
delicious , naturaly lost the link.

Where can I find list of most popular delicious like sites, prefereably with 16x16 icons ?

My only interest here is that users would add bookmark to my site with click on icon.

hmm there is one link for icons:

http://bestdesignoptions.com/?p=1716
no 16x16 as I see

looking for code to fit under that images .....

http://dryicons.com/free-icons/preview/socialize-icons-set/

?

that PNG sets include 16x16 versions for about 16 social networking sites

hmm mybe this is what I was looking for:

http://www.addthis.com/web-button-select

yes, there's that too :p

another neat one
