I think there is another big problems with the "mini-Facebook" live feed in the top right corner which I haven't seen mentioned much:

What is the usefulness of this information? Why am I supposed to care that College Acquaintance A commented on Person I Don't Know's photo? How is this useful to me? 80% of the items in the live feed are noise like this, and 15% of the remaining are items that I can see in the main feed itself.

This, along with the Read/Watched/etc buttons just seem to lower the signal-to-noise ratio.
