I've been building something similar to this as a side project. I think it's a great idea and hope these guys can build a better app than I've been able to.<p>Here are some of the benefits of this approach:<p>* <i>It's more than just to-do lists.</i> Lists can be used to keep track of everything in your life, not just the things you need to do tomorrow. Gift ideas, checklists, links to read later, restaurants to try out, data you've been collecting, pros and cons, brainstorming sessions, and life goals (to name a few) can all be represented as lists.<p>* <i>Mix to-do items and random thoughts.</i> Not everything on a list should be something you're going to follow through on. Sometimes it's good just to get your thoughts out of your head and onto a screen. You can evaluate your ideas later. Think of your lists as brainstorming devices, especially if your brainstorming session is spread out over many hours, days, or weeks.<p>* <i>Every project needs a list (hashtag).</i> If you're undertaking something you'd consider a 'project,' make a list for it. Start collecting thoughts, goals, links, notes, and of course to-do items.<p>best of luck to you guys!
