I think the Home feed of the algorithm seems to be prioritizing images or something, which makes sense in theory I guess it's more engaging medium, but in practice I get a lot of random gm photos from people I don't know/follow

Seen this and also some comments about casts having frames being de-boosted etc.

Want to clearly state: there is no impact on your cast distribution per its image, video or frame attachment.

It is all about the cast engagement. (Always has been)

If your casts with frames are not doing as well as your casts without — it is probably because people find them less interesting.

If your casts do better with images vs. not — it is probably because people find them more interesting and engage with more.
