I don't use them because I have to know which pages are important enough to bookmark when I come across them first, rather than when I need them later.
Usually I rely on finding something in my history. If I need to get around to it at some point, I'll keep the tab open and I'll get around to it when (if ever) I'm closing a bunch of tabs in a row, which takes relatively little effort. If I bookmark it, it'll just sit there and I'll never think of it again.
