I have no issues against you using your method, I'm glad it works for you, but I can't see how this could possibly help the majority of of people.
> Now: Keep them in your browser, local to you.
What do you mean by local, I wanted them synced with my phone and my three other computers, but I may have misunderstood you.
> Keep the frequently-used ones right in front of you in the bookmark toolbar.
How often do I have to rearrange them? Or delete them? Or send them to the later? Or should I just keep adding them to the toolbar until they naturally disappear and create an endless mess of unsorted bookmarks?
> Later: Link blog them (on Tumblr or G+ may be). Or you can even keep them local to you using above number 1 perspective.
Why would I, it seems so much more trouble? I'd rather bookmark them in a folder named later.
> Future: Don't worry about loosing the bookmarks you have already consumed and not going to come back to them anytime soon. Again, if you're link-blogging the content you feel you need to save, than you don't need to worry about future.
This is the one I disagree the most! This isn't a shift in perspective, it's ignoring the problem, I go back to my bookmarks months (years?) after I've booked marked them, and I'm happy to find them.

Honestly I manage my bookmarks pretty well with chrome now-a-days specially with the built in sync system, I'm very happy I don't have to worry about sync anymore, I even have them in my phone all the time.
What honestly I think is missing is better search, you can only search by title or URL as it is. The URL of an old enough one is virtually impossible to remember and the title so many times doesn't help much either, you might not remember it or it might be a smart ass title that is not a good description of the topic in question, so many times I end up finding it quicker in Google by inputting the text I remember rather that going through my bookmarks, since I tend to remember the essence of the article.
I think labels would also help since an hierarchical organization that would actually help would be insane, I'd rather write a couple of words referring to the article, but the truth is most of the times I can be bothered.
So yes, I agree with the author, it is not an easy problem.
