A few months ago I made a post about comparing three web sites in terms of the usefulness of each for collating links of related materials. This is a slight expansion of my prior concept and map. Branches can be used not only to show positions (rank, size, weight) but also the “reasons” for the position.
As before, in reference to the original title “Pinterest Pins Scoop.it and PearlTrees,” I am referring to “pin” in the context of wrestling.
Pinterest, Scoop.it, and PearlTrees compete in the same space to be the best web-based way to refer readers of your blog, tweet stream, or web site to alternate sources of information.
