gmail has been my bookmark system for 2 years, since I found toread.cc .
virtually everything, I found interesting while surfing and browsing, I will just hit my toread.cc script in the booksmarks, and it goes with link to my gmail account.
till now, I have 40,000 *emails* or links in my gmail account, of course, not all from toread.cc, but half of them? sure.
and if I need something, I just use some keywords, and gmail usually gives me the correct file I was looking for.
Rather than google.com, which might also have lots of junk in between the results.
