I can't speak for the GP but I agree it's a bad idea. Maybe not for everyone, but for a certain type of person, definitely.
The problem is psychological. When you talk about an idea, you feel like you've somehow accomplished something by doing so. You hear other people's positive reactions and instead of validating that your idea should be done your brain interprets them as satisfaction in and of itself. You feel that little less "hungry" and yet you haven't even done anything.
Also, talking too much clouds the vision and you tend to expand the scope even as you talk. Your companion will have their own opinion and their feedback and ideas will merge with what you think until you're left with a union of both party's concepts, your version 0.1 getting that little bit harder to ever reach. Or worse, that person might later claim you stole their ideas.
I come from the school that believes that with very few exceptions mere ideas are nearly worthless in themselves. Anyone can imagine anything. Actually doing things is much, much harder. Talking is not doing. Don't talk to anyone until you've got at least a prototype, IMO. With modern web frameworks you should be able to whip up at least a crappy, incomplete prototype outline in a day or two. Sitting down and doing that will hone and focus your thinking. And if you can't be bothered spending a day or two implementing just the skeleton of your idea - then you obviously don't really believe it's a good idea at all, so go and think harder : D
From my experience, ideas are worthless because they don't exist. Sounds obvious but think of it is this way:
Everything can fit neatly and beautifully into anything else whilst it exists in your head. "How do we monetize this...? Easy! just do xyz!" The answers are clear, the solutions are elegant, and everyone and everything is holding hands, dancing around in a circle, singing their hearts out.
As soon as you actually get to work, and you make the transition from fantasy to reality, well: shit instantly hits the fan, and you've got a mess of a mess of a mess, and that's what really counts. Nothing works right, nobody wants it, you deal with endless bugs, its never ready, all your "plans" don't really mesh with this thing called reality.
It's kind of like fighting in a video game. You can fantasize all you want about how badass you are at street fighter. But get yourself into a real street fight and you won't ever think you know anything about anything ever again.
