Long ago I realized that it’s often better not to quit a suspected bad idea, but to explore it and learn from it. @substack just gave me more insight into this:

Don’t unpublish your bad ideas. The best argument against a bad idea is to implement it well.

James Halliday (@substack)

The last sentence is key, and applies to more than published bad ideas. In web development, if it is indeed a bad idea, you’re more likely to learn from it, than to cause harm. If it’s a good idea that seems like it’s a bad idea, which turns out to be a good idea, it might be a really good idea.
