I suspect you can increase your conversion rate to paid quite easily. I've been using the free version for sometime. And I have no idea if the paid version gives me the improvements that I care about. I'm sure a 7 day trial, or an explainer video that walks through the differences would go a long way.

For what it's worth, there's a lot of functionality that I want removed from reddit. I've never crossposted, yet often click that link because it's next to 'hide'. I hate the hide link and would rather have 'hide everything above'. On old.reddit.com many of the links are too small, so increasing their size would be nice. Just a few things off the top of my head.
