I have quickly become a huge fan of Trizle, but do find flaws with logic.  I suppose any idea could expand infinitely and Trizle does a great job of weeding out that garbage.  Here are my like and dislikes on this:

Likes:

• Suggestion of grouping like tasks (task creation and task completion)
• Over simplification - Gives me actionable steps.

Dislikes:

• Over simplification - You can’t just make tasks, they need to be good ones.
• This sort of time parsing is rarely possible.

Suggestions to get things done:

• Keep a todo list close by.
• Jot down things as they come up, but do nothing with them.
• At the end of the day take 15 minutes to formalize them and prioritize them.
• Next day start with #1 instead of trying to think of what to do.
