Personally, I've found Workflowy [<a href="https://workflowy.com" rel="nofollow">https://workflowy.com</a>] to be indispensable not just for keeping track of ideas, but for then turning those ideas into something real.<p>Loads in any browser, has a (barebones) mobile app, and it's great for collaboration. I just hope their business model is enough to keep them afloat :/
Good use of Trello.<p>If I can give you feedback on your lists, I would say you are approaching markets in way that will likely have you paddling upstream for years to come.<p>Here's the thing: You don't have to come up with the problem to be an entrepreneur. Other people have problems. Lots of problems.<p>Your job is to create their solution.<p>I mean no disrespect--on the contrary, I'm trying to help.<p>Now, I can't see the details of your board, but how many people are trying to combine a pen and music? Sure, they might want to flaunt your awesome solution after they see it, but more than likely, they'll continue along with their life and not give your idea the time of day. Even it it's awesome and you execute flawlessly. Brookstone isn't even a big retailer in the scope of things.<p>Alternatively, talk to someone in any job. Really, any job will do.<p>Ask them about their challenges. Their problems. What sucks. What they wish they could do. I'll bet more people have complaints about their jobs&processes than want to combine pens and music.<p>So go ask people about what they don't like. And even if your impromptu focus group of 1 isn't forthcoming, this is where you lead. Wave your hands and invent solutions on the fly. Double credit if you can make these solutions with computers. Do any of your ideas strike their fancy?<p>Congratulations, hone in on it, then go talk to more people with that same job and see if the problem exists...repeat and tweak, you might have a real thing.<p>I've found that understanding, and then solving other people's problems is remarkably powerful and lucrative. You don't need to invent problems since people have enough big ones already.<p>Put a few on Trello, and solve one.
I track my ideas using Trello too. If that list in the screenshot is all you got so far, I have a bit more, and I have ordered them differently. In my case, 99% of the ideas I will probably never take action on, so it's a bit weird to track their phase. Instead I have separate lists for how big the idea is, how much time/energy it would take to implement.<p>Then the order in the list defines how attracted I am to actually doing the idea at the moment. So for example, making a Facebook competitor would be in my 'big ideas' list, but all the way at the bottom, because I think it's not very likely to end well.<p>I browse over my ideas every now and then, and update the ideas with information about how I would go about implementing them if I chose to. I usually move ideas up the lists when they come back in dreams or I find myself thinking about them during the day.<p>I have a few ideas I am actually doing work on (architecting, exploring, programming) and I move them to a separate 'doing' list. They also have their own Trello boards of course.
This is exactly what I do - I also add label colours to differentiate categories. I've also made "Stupid/abandoned" list, so that I don't just delete my ideas, but put them there just in case. I find it helpful to review it every now and then. Then I access them on my mobile too! It's a great tool.
How about org-mode:<p><a href="http://orgmode.org/" rel="nofollow">http://orgmode.org/</a><p>Emacs extension = is this hacker news or what?
I started using Trello for this a couple of months ago. My "project" board has 4 lists: Ideas, Queue, Work-in-progress (It was "building" until I read your post), and Launched.<p>I like "work-in-progress" better than "building" because I use this board for more than just product-type ideas; I also use it for things like "learn about X" or "try Y."
