I love how easy it was for me to create my own lists of things we need to get done in our business and share them with others via email.
Also love that this service allows us to use their mobile apps so that we don't have to do all our tasks from an office computer! The only thing I would like to see added are more templates available (maybe even some free ones). Definitely worth looking into if you want something easier than using Excel spreadsheets to keep track of your personal projects. We're able to easily store information about what needs doing next, when someone else will do it etc., without having to rely solely upon written notes/email communications.
