Sure!
I also wonder about the points you made above. I'm afraid I don't have much insight. A previous Pickering fellow did let me know regarding fellow profiles, that Rangel seems to assemble cohorts consisting primarily of people of color, whereas Pickering tends to lean more towards diversity in broader terms. Of course, there's no way to know if this is intentional or just how pieces fall, but it will be interesting to see if that observation holds.
