Would you spend $5 to dodge a failure you haven't faced yet?

We're working on a new social network for entrepreneurs.
The idea is simple: people share their real business experiences, including failures, and others can learn from it.

Here's the question: if you saw a post where someone describes a mistake they made that cost them time, money, or reputation, and their advice could help you avoid the same trap, would you pay $5 (or more) to unlock it?
