I am a huge fan of Delicious http://delicious.com/jamison , and I recently installed Google Chrome. Suprise there are not Delicious addins for Chrome.
Fernando Correia has posted a great set of instructions for using bookmarklet’s to mimic the Delicious addin for Firefox. The only think lacking is the sidebar.

Update 6/30/2009
Delicious has added instructions to their site too.
