Social+Bookmarking

Bookmarking is the most common form of "web curation' or keeping track of useful "stuff" on the web. It has several forms and uses from casual sharing of cool things you've seen like Pinterest, to hardcore annotative research tools that allow you to build bibliography notations as you go. Know what you want to do with your "stuff" before putting tons of effort into creating your collection or pretty soon your "stuff" will be spread all over the universe in various apps and clouds you've experimented with...which doesn't help you keep track of it at all! :) (Voice of experience here, ahem.)
