My "workfow" for this is such:

While surfing around the internet I find interesting things. I high light a section of text and add it to my diigo list. I then have system which sucks in the rss feed of my diigo list and combines it with a bunch of other rss feeds (youtube and vimeo favourites, my wordpress blog, etc) to populate a website: http://fuzzyslogic.com

I only occasionally search back through my diigo list. I use tags to allow me to filter content on the fl.com site.
