Born and raised in a conservative, predominantly Christian Philippines, baptized and raised Catholic, hell I never went to a non-Catholic school my entire 23 years of life. Turned out to be agnostic, or whatever, I don't care. I just don't pretend to know what I really don't.
HAHA no, you're not gonna love her forever, you silly horny little kid.
Here's what I personally did when I had an idea for a startup:
1. Decide where it's going to be most useful & get a lot of traction: desktop, web, or mobile. I had no second thoughts about going mobile since the problem I was trying to solve was mobile-related.
2. Design the screens. It doesn't have to be pretty, and don't take too much time doing it because whatever you write down will 1: most likely change during the dev process, and 2: most likely change upon testing it with your users and receiving feedback. Just use it as a guide. Then, code.
3. I don't think investors would be willing to give you some seed fund for a product that doesn't even exist yet. So definitely get started with at least a working prototype, would be great if you have some data to back that up (what did your users say, how many downloads have you had, how much money did you make from it, etc etc).
I confirm this. Was working on an app prototype and when I reloaded the page it couldn't find it.
How I store my ideas now: Evernote, 'nuff said. However notes are organized in Evernote seems to be the perfect way for me to organize my ideas. I can just create a separate note or notebook to collect all the related ideas in one place, and I can write down my ideas in the most organic form possible.
Also, some critiques on the app's features based on what's written above:
1. People probably don't want to use an app for organizing ideas that actually SHARES those ideas with other people.
2. When I have an idea that's still a little abstract, I think the idea pointing system is kind of useless because obviously I'll have to spend more time thinking about it, but I still have to write it down. I'm just saying, it doesn't always have to be put out in the open for feedback right away.
3. Idea validation is, from my experience, better off done via conversation with the people you trust the most. So either I'm saying that automating that process is less useful, OR you can make the app a bit more social by allowing only a user's most trusted friends to evaluate the idea. That way you don't scare away people from your app because of number 1.
