Story. I had an opportunity to sit in a physical PC meeting of a major conference as a scribe. A paper was discussed. It received 5 Weak Accepts/Rejects; no champion; no hater. The decision was leaning to a rejection; the discussion lead commented, “it’s just too boring.” 1/5

@roopshasamanta @mboehme_ Yup! When your paper can get rejected for reasons like "no one is excited about it", it's really got to do more with who is on the PC rather than your paper itself. Maybe the folks who would have liked your paper declined the PC invitation for some reason.

Why some graduate programs force recommendation letters to be sent in Nov and early Dec? It's hard to write thoughtful, substantive letters during the chaotic EOY period, and I wonder anyone even looks at PhD/MS applications before the new year (let alone making decisions).
