Maybe, but image posts drive more engagement than text ones. You can see on !lowqualityfacts@lemmy.zip that the text posts, which are no worse LQFs than any other ones IMO, score noticeably lower.

I like sites / Lemmy frontends that provide some kind of 'teaser' for text posts (they also show a bit of the post's body in the main feed), meaning you can often see both the feed line and the punchline for a post without going into it (it works well for 'dad jokes' for example). But the default frontend - lemmy-ui - doesn't do that, so it hobbles the potential of text posts.
