I also found it difficult to engage with Asana and Trello (also Evernote, less so). You make a good point, its the limited nature, constraints, that stop me from using task managers for all my projects. While, they have worked for specific projects, including personal and team initiatives, my day to day to-dos don't always make it on the board. What I have found is Evernote and OneNote, are more flexible and I can dump more information in a less-structured manner. For me its all about stickiness factor... In the last 6 months, I have gone full-ham on OneNote, and now use it for team collaboration and personal use. A big part of it is the "open" feel of a blank canvas. At the same time, I can create and save templates for tasks or projects that fall into specific work buckets. Also, for teams, OneNote is free to use and has great iOS and Android apps (webapp is fine too). My current gripe with OneNote is the lack of push-notifications of completed tasks.
