Today's guest blogger is  Caitlin Casey , a McCue Postdoctoral Fellow at UC Irvine who studies galaxy formation and evolution, including discovering and characterizing diverse types of starburst galaxies and how they relate to more "normal" spiral galaxies in the early Universe. Caitlin recently cowrote, along with Kartik Sheth, a NatureJobs article entitled  The Ethical Gray Zone , based on an extensive community poll on ethics and diversity. She is also involved in STEM outreach and mentoring within her department and throughout astronomy.   This post was originally published at Women in Astronomy .  I recently found myself in a heated internet debate on the concept of white, male privilege and whether or not affirmative action was necessary.

For what it's worth = 4 syllables Ef Double-you Eye Double-you = 8 syllables Saying the acronym takes twice as much time as just saying the words. Doesn't this defeat the purpose of an abbreviation [1]? People, just say the words! [1] While I'm at it, why is "abbreviation" such a long, hard-to-spell word? I'm going to just start writing Abv.
