Generalization of SylvesterGallai theorem
@Dal: The proof uses some considerations using the Euler characteristic, results on points on (cubic) curves, and ideas from additive combinatorics to force structure in configurations having few ordinary lines. You could also look at Tao's blog post: terrytao.wordpress.com/2012/08/24/…

Cardinality of the prime divisor set of a kpower sum
This follows from the finiteness of solutions to the $S$unit equation. See for example the main theorem in math.uwaterloo.ca/puremathematics/sites/ca.puremathematics/… . Maybe there's an easier proof ...

Graduate program applications that require questionnaires and other nonletter material
By the way, even the streamlined process we now have for MathJobs might be under threat  this year, three universities made me upload letters for job candidates at their website rather than getting it themselves from Math Jobs. (Rochester, Vermont and North Carolina). I hope this infection doesn't spread, or that people will take steps in advance to resist it before too late.
