I accept that making quality content and real engagement among users are similarly significant for this stage. A variety of quality content is beneficial in capturing the interest of a wide variety of users and investors as well.

Both are vital. Quality posts could potentially drive more engagement among the users. On the off chance that the content doesn't add value to the platform, there would be nothing to keep individuals drew in on the stage. So, quality content and engagement are required since one causes the other to occur.

That being said, there are instances that long-form content doesn't attract that much attention or engagement while short-form content might get hundreds of comments. There are isolated incidents like this in which what we think about high-quality content doesn't necessarily result in our expectations. One good reason for that is when a topic is relevant enough that the others would want to participate in a discussion or even a debate. For this case, quality content becomes irrelevant since the focus of the users is to react by sharing their opinion about the matter.

Not every person is a decent creator, but rather everyone can take an interest in a conversation. There are authors who are keen to create interesting topics and even controversial ones that the others are more than willing to take part in a discussion.

Engagement is made from the content that appeals to the masses. Not many will be attracted if the content in this platform will be too niche or too crypto-ish. There ought to be variety and everybody ought to be offered an equivalent chance to get their posts seen on the Trending page to feel motivated enough to keep participating in this platform. 

That way, bunches of individuals would invest more effort in their posts and create a snowball effect across the whole platform.

So, to answer the question... BOTH! It's equally important for the long-term sustenance of this platform.
