Tags never work that well for me. Eventually I have far too many of them. Sure, they're better than nothing, but only just.

I've just started using Circus Ponies' Notebook 3.0 for organizing my writing life. I've got so many snippets, projects etc. I'm slowly setting up a notebook for this. Gonna take me a while.

What I'm doing is using the traditional computer folder structure with as much organization as I can muster. Then I create a notebook page for each project or idea and link (not embed) the files for that project on the page. Also, I can enter notes about the project, set up action boxes and due dates for submissions, keep a record of rejections and acceptances, and so forth.

It's already working well for me. Good way to keep track of revisions and the things you need to do for several different projects. The only bad thing is that I didn't start doing this years ago.
