It's great that on those pages, if you hover over a resource title you see a popup with some basic info about the resource. Note that there's no visual cue that such behavior exists - you have to serendipitously hover over a title to find it.
What doesn't make sense is that if you click the "Learn more" link on the popup, you're given another popup with almost no extra information.
I'm pretty sure that most people would expect that clicking "Learn more" would take you to the detail page for the resource (preferably in a different tab). In any case, that behavior needs to be provided from the upgrade / comparison pages - direct links to the resource detail pages.
Thanks,
