I have been bookmarking on my (second) site for a while now. In the past I used Diigo, but I would save everything without much thought. I tinkered with Radio3, but it just did not work for what I was after.
I feel posting on my site has made me more conscious of what I save and share. I have progressively extended this too incorporating the various post kinds.
Before I save bookmarks, I use a combination of Pocket and Trello as a temporary store. I have documented this here.
Hope that helps.
