I figure out how to use the best of Trello and the best of RTM for a formidable GTD workflow.
Dave and Gunnar talk about UEFI, Red Hat Storage, Remember the Milk, and the most badass of the badass innovators.
I've been using Remember the Milk to manage my tasks for a while now. It's a mostly good platform. I like the number of possible clients and interfaces it provides. Between lists, tags, and the very powerful Smart Lists feature, RTM makes it very simple to organize some fairly complicated workflows. If you're into that. Which I am.
