Someday soon I will be releasing a podcast and we did a review of your Show HN. Check it out if you want.

Nobody [here] will give you their email without an example demonstrating it's worth the sacrifice.

Didn't understand for sure how to add topics... comma delimited?

Releasing a Show HN with no effort on HN beyond a link also doesn't go far.

Thanks for the feedback. I agree that having a better example on the main page would be ideal! I will work on the topic adding interface to make it more intuitive :)
