As an example of something that I think would be really useful, Matthew Kidd has talked about adding a feature to BBO Helper as follows:
"A bigger idea is to provide a heads-up display of your opponent's style based on their playing history, classifying actions along both aggressiveness and wildness dimensions. So for takeout doubles, where a player averages on an (HCP + distribution points) histogram would measure their aggressive while their proclivity to make off-shape doubles would measure their wildness, e.g. a takeout double with 5-3 in the majors or a stiff in the clubs when 1♦ was opened, would drive up your wildness score, and a doubleton in an unbid major even more so. Similarly one can examine two-level overcalls, perhaps with a special statistic for how often they overcall on 5-3-3-2 shapeyou see a lot of this even in open ACBL events; sometimes it can't be punished but sometimes it merely goes unpunished."

Maybe it would be interesting to poll experts about what unanswered questions they think are most worth solving. It might also be useful to think about what BBO could do to help further this type of research. For example, if everyone was forced to click on a radio button to describe their basic system, would that make this kind of research easier? What else could BBO do to facilitate research?

I haven't personally mined the myhands data but I have done some mining of the vugraph archive. So far this has lead to an article in the IMP magazine about effectiveness of preempt styles, but there are lots of other things one can look into in the vugraph archive.
I know that other people are working on analysing real or simulated bridge data. But above all, as jdiana suggests, it would be good to hear from other BBO folks what kind of research questions they would find interesting.
