I'm also following a GTD-like approach (and I strongly second the recommendation on the book)

My Trello board has the following columns:

- MAYBE - for things that I'll maybe do

- BACKLOG - for things that I decided I'll do at some point

- WEEK - for things that I'll do this week (limit: 8 items)

- TODAY - for things I'll do today (limit: 5 items)

- DONE - move things here once done

Once a week I do a review session where I clean the "DONE" column and reshuffle things in the other columns as needed

Hmm,I hadn’t thought of a week/day in Trello. It’s an interesting idea, but having a les productive week seems like it really screws things up by forcing moving back to Maybe and Backlog while you plan out your week. But i see a possible benifit in that.

I wouldn’t do that to my collaborative work board, but for a personal board that seems interesting.

Here's my setup, it's pretty similar to the other person's:

Followup: stuff that I'm blocked on (e.g. maybe I'm waiting on someone, maybe I have to let something run for some time, etc)

Doing: stuff I'm actively working on

To Do: stuff I plan to do in the near term

Inbox: everything starts here

Backlog: stuff I want to eventually do

Anything I finish I archive.
