If you want to potentially sidestep some of people's frustrations you might consider just using the credibility rating and focusing on whether a group provides factual reporting, rather than left or right of center

You can also create a user experience that more carefully manages expectations of the feature by having it be opt in, but presenting the option to users when it becomes available. That gives you the opportunity to give a short blurb acknowledging its imperfections and also highlighting its potential value

As someone fairly to the left wing myself, the fact that lemmy is so left wing is both a blessing and a curse. I don't see Nazis around, but being in an echo chamber isn't great for your ability to engage with perspectives other than your own, and makes you succeptible to narratives that reinforce your existing views regardless of whether they're accurate

I'd love this feature, in spite of its flaws, but it does definitely have them. Its based on the US overton window, which will frustrate folks from other parts of the world who may already feel lemmy sometimes forgets the world beyond the US exists. And the US overton window is changing as a product of the trump administration which may warp mbfc results, which could honestly be really dangerous.

Focussing on the factuality and credibility might help you sidestep those problems and make a feature people would find less frustrating, potentially even to the point that you could make it opt out.

Generally I appreciate efforts to build healthier, less echo chambery discourse, thanks for the work you're doing ❤️
