A marketing message!

So, you've created a "prism" - essentially a curated collection of popular content - featuring the top posts from the past few days. And, you're encouraging people to visit makeprisms.com/gold to upgrade their subscription status to Gold.

Here's what I can infer:

* The platform where this prism is being shared likely has a reputation or ranking system (e.g., likes, comments, shares, etc.) for posts.
* Users who don't have the Gold subscription might not see the top content in its entirety or with all features.
* The goal of this message is to entice users to upgrade to Gold, presumably to gain access to premium features, exclusive content, or a more comprehensive experience.

If I'm correct, this post is an example of a marketing strategy aimed at upselling subscribers. Am I right?
