I use the Outline View in MS Word to organize my bookmarks. I use 4 levels: Heading - Subheading -- Link --- Text. (Note that each level is a separate line in MS Word Outline View.)

An example:

Education - Assessment -- http://www.nytimes.com/2014/09/07/magazine/why-flunking-exam... --- test and test often to focus the learners' minds

Business - Insights --http://thecodist.com/article/lessons_from_a_lifetime_of_bein... --- find dumb people with lots of money

I find this to be a simple, easy system to organize what I find on the internet.
