Actually, we are not planning to charge for the guide. The goal of the guide is to help startups. Startups don't have extra money to spend, so we're not hoping to make money off them anyways. We'll have other premium features in the future to make some dough :)

Yet requiring them to signup to see the guide will help you build a list of potential users for your premium features.

Well also true. we are trying to just get more users to get feedback, but I guess making it unlocked by signup would give us more "serious" users.

Not sure if you took his advice. I can't see anything without registering.. which means I'm not going to bother.

FWIW you can still access the content/guide without signing up - You can click your way to the guide/content which is still possible now.

I didn't link out of courtesy since they want to acquire users to gather feedback.
