Hm, would you expand on what you disliked about the integration? You're using the bookmarklet, right? I just click on "pin this" whenever I want to save the current webpage, and click on "my pinboard" whenever I want to look for a bookmark.
The killer feature for me is being able to type in a description for each bookmark, because later on you can search by any word in that description.
I've given up on tagging anything though.
