Ideas are not just cheap, the huge majority of them are actually bad. Most ideas are actually not worth the time to consider them.

If you want a repository for good ideas, I think first you need to find a way to filter the bad ones.

You are spot on. After checking some recommended sites here (e.g. /r/appideas) it's clear that a lot of people just shitting out (for lack of a better word) ideas without half of a thought on execution. I think there are a particular kind of people who do this. The kind who wants to patent everything and always looking for the Next Big Thing™.

I have no solution for this other then focusing on the following things:

    - How detailed the idea is. The mere fact that someone took the time to think about it and write it down (1-2 page at least) is a good first filter that throws out things such as "It's like tinder but for job search".

    - Limiting it to "technical" people who has experience with actual execution of ideas and instinctively point out problems

And if you could do that reliably, you should already be a billionaire from your many successful startups.

Success is 1% inspiration 99% perspiration.

Being successful at business is a different skillset than having good technical ideas. The best idea in the world won't build you a sales force magically nor will it put into place a manufacturing chain for you.

[NateEag]

Yes, agreed.

But if you can consistently predict whether an idea is "good", by definition you should be either hitting it out of the park consistently or getting massive returns on investments.
