It's creating a "wall of text" effect to me and I'm not able to quickly skim and allow my eye to catch the bits that are interesting to me.
As a comparison, the HN homepage is very accessible to me for skimming and finding things to click into (like this entry).
UI is often quite subjective, understood. But I can't really "scan" the first view fast enough. It's all blending together and causes extra processing on my mind.
