Yelp put a data set online for people to play with, including reviews, star ratings, etc. This could be a really neat data set for a student project. The data they have made available focuses on the area around 30 universities. My alma mater is one of them. A sort of goofy talk about how to choose the optimal marriage partner when viewing the problem as an optimal stopping problem.
I know we need a new journal like we need a good poke in the eye. But I got fired up by the recent discussion of open science (by Paul Krugman and others) and the seriously misguided Research Works Act- that aimed to make it illegal to deposit published papers funded by the government in Pubmed central or other open access databases. I also realized that I spend a huge amount of time/effort on the following things: (1) waiting for reviews (typically months), (2) addressing reviewer comments that are unrelated to the accuracy of my work - just adding citations to referees papers or doing additional simulations, and (3) resubmitting rejected papers to new journals - this is a huge time suck since I have to reformat, etc.
