Organizing Scheme for Bookmarks

I'm attempting to organize my Firefox bookmarks. I'm looking at about 2410 (now down to 2382) links, hopefully some being duplicates or just variations on a main feature. Below I have laid out, as clearly and distinctly as I can, the recommended groupings, such as category specificity and when to create a new folder / new category.

  1. Create new folder when there are more than 2 possible links within a new category.
  2. Category should be subdivided for the following two reasons:
  3. To avoid adding too much scrolling, broader categories can be grouped further into even more generalized groupings.
