I saw those pages, but they read like tutorials for people already sold into the idea and just needed help implementing some of the features. What I thought was really missing was selling the benefits of those features before trying to explain to someone the steps needed to use them. I think that's where the gap is on the landing page. As currently it goes from Short Definition of Feature -> Tutorial on How to Use Feature. I think what potential users really need to more content about why the feature is beneficial to them and a very succinct overview on how it works.

Good luck!
