Regardless of the system, I’m a big fan of getting things done. That’s in the lower case context of completing things. I’m still waiting on my library to get me David Allen’s book, but I’ve read enough to be familiar with the system. I’m more interested the parts of the book that don’t get covered much in blog posts. Especially how he approaches the daily/weekly review process. But as for the actual GTD todo list—with next actions, etc.
