Delicious shutting down bummed me out quite a bit - I used it heavily for many years. For the moment I use a combination of my own private wiki (for long-term keeping) and Pocket for short-term keeping, either if I want to read something soon and don't intend to keep the URL around, or until I find time to add it to the wiki.
Right or wrong, I just use the default bookmark manager which comes with Google Chrome, No need for extra extensions or web sites etc, just the bare bones installation works for me.
I use Google Chrome about 95% when I'm using a web browser on my desktop. I'm signed into Google with my Google account and my bookmarks stay with me on both my desktop and my many Android devices. If I make a bookmark with Chrome on my desktop it shows up automatically on my Android device and vice versa.
I'm well aware that Google has the ability to track what I'm doing when I'm using Google Chrome especially when I'm signed in with my Google account.
I guess the question becomes
"What do you need from you bookmark management software?"

I use Google chrome too. It allows you to switch profiles too which is handy if you have more than one person sharing the machine.
Just logging into the browser is enough to get all the bookmarks, forms autofill and similar to work out of the box.
