Social Finance (SoFi) raised a billion dollar round. Boo-yah. Since unicorns, EUnicorns, decacorns, centaurs, etc were not enough, these billion dollar round companies have been deemed by some as dragons. </vomit>
BTW, there are some recent great essays about the problems with our unicorn mania. Mark Suster of Upfront Ventures penned a great post on it as did Michael Eisenberg of Aleph who argues it's tearing the heart out of entrepreneurship.
My recent favorite is by Caterina Fake, co-founder of Flickr, who writes about the merit of being a cockroach.
