Ask HN: What is your information management workflow?

For a little while I've been using successfully a workflow to manage my read-watch-keep list. Here it is: Sources of information: - Tweets - Hacker News - Google Reader If I'm using the computer or iPhone I usually add stuff first to Read It Later list using Chrome and Echofon plugins respectively. Later, when I get some time I: - Read/Watch it if it's fast enough and use Delicious to bookmark for future reference if appropriately - Add to Instapaper if it is something I want to read in Kindle (big article for example) and to Deliocious if is also somethin I would like to keep - Remove from Read It Later list I'm using RIL mostly as a staging area for stuff I wanna see later and Instapaper as a way to send big stuff to Kindle. However I do not have any kind of system/app to keep an updated list of books to read or videos/presentations to watch. Looking for something to help in this area. What about your workflow?
