There are dozens of bookmarking services out there to help you organize links from all over the web. Although I was once an avid del.icio.us user, I can't say I rely on any of these services anymore. Besides occasionally hitting the "Read later" bookmarklet to save interesting articles I encounter while browsing the web onto Instapaper, I've mostly turned back to the stock bookmarking function of Chrome.
A lot of people were upset when news broke that Xmarks was closing shop though -- and were glad to see it found a new home -- while a few others were worried when Yahoo let slip that it was looking to get rid of their bookmarking tool Delicious that it bought years ago.
With that in mind we want to know: do you rely on your browser's bookmarks feature or on a specialized service / add-on? If it's the latter, tell us what you are using and why you like it.
