Over time, I have come to realize that what usually constitutes a startup idea is very hard to "share". Sure, you can express it in words, but an idea in your head is usually far more subtle than the words you can string together to convey it.

Edit: grammar

That's why people make such a big deal about an elevator pitch.

If you can't express it as an elevator pitch, it's probably not a fully formed idea.
