It's build in already. Just unsubscribe from shitty subreddits and subscribe to quality ones.
The mods from quality subreddits are pretty fierce on enforcing rules against memes/low quality comments/etc.

What are the highest quality sub-reddits that don't allow memes?
/r/askscience/ and /r/AskHistorians/, for instance.

This doesn't work on r/all, which is a great place to find new content you haven't discovered yet.
Plenty of individual subreddits ban memes and pics for precisely this reason, because there is a broad recognition that they will tend to swamp more in-depth content.
The nice thing about Reddit is that if you want some low-brow content, you can get that, too: users can easily customize what they see by selecting different subreddits, relative to Facebook.
Facebook is overtaking reddit in the Quality algorithm department.
