PRODUCTIVITY 2.0: 171 ways to improve task & project management individually, for your team, company, organization or family

I've merged the former COLLABORATE 2.0 and ORGANIZE 2.0 categories under this new lable. Still some overlap with the KNOWLEDGE 2.0 and OFFICE 2.0 indexes - will try to weed them out a next time.

In earlier days each and every project-based organization had a moment where someone decided to buy an elaborate, colorful planning system - and most often abandoned it after a few weeks. I wonder how many of the solutions in this list - offering planning & task management for individuals and groups - are subject to a similar destiny. Even the majority of the best ones lack sufficient logic and usability.

I've italized the numerous new additions in this update.
