I don't think I've ever heard people say that ideas are entirely worthless. Good ideas have enormous potential value.

The argument is that, in general, unlocking this potential requires great execution. You can't (in general) make a good idea successful without it. You can, on the other hand, take bad or boring or tired ideas and make them successful with great execution.

So, great execution (in general) matters more than great ideas.

I've had bad experiences trying to share ideas with people online.

Sorry to hear that. I know how it feels -- anytime I share anything online (my blog posts, my open source projects, etc.), I get beaten up by a vocal subset of readers. Sometimes they're well meaning, and sometimes they're just jerks (and sometimes both.)

I've learned over the decades that any feedback is good feedback, and it helps to stay optimistic, and keep trying anyway.

Good luck to you!

That's not unique to sharing ideas, unfortunately. Lots of people actually share their implementations, and also get beaten over the head with a stick...
