I briefly met a graduate student at the NCTM Regional Conference in Chicago last month. At least some of her dissertation data is coming from an online survey, which she was working very hard to promote. She put up with quite a grilling from me about her interests, plans, etc.
If you have the 10—15 minutes to spare to contribute to her survey, it will surely be repaid karmically many times over.
Grad school is grueling stuff.
Give her a hand if you can.
