That works for Tabs - I just spent 10 minutes watching my browsing behavior, and realized the only thing I look at in Tabs, is the Favicon.

Personally, Google has replaced my bookmarking behavior. I don't bookmark pages any more - when I need to search for them, I just google for the appropriate keywords. In fact, this works so well, it's rare that I even need to add a "site:" to give a hint as to which site to look for it.
