I've always like sports and stats, so mixing the two is an interest of mine. Glad to see this new forum.
I was always fascinated by baseball stats as a boy, and reading Bill James as a teenage started me thinking about which stats were important. From there, branched out to hockey with the Hockey Compendium and basketball with Dean Oliver's work. Minored in stats in university.
Main area of interest statistically: Historical stuff (because I like history and because there's a decent sample size
)
Pet peeves: Traditional hockey people who bash advanced stats as number-crunching but rely heavily on traditional stats. Hockey analysts who don't understand the underlying assumptions they have made in their studies, don't understand the importance of the context in which their numbers were generated, and overstate their conclusions. (If Dave Berri ever starts analyzing hockey I will probably spend all my hockey stats time picking his work apart.)
Hope to see more data gathering for future hockey analysis. IMO hockey analysis is heavily constrained by available data, and collecting more data is the best way to improve our knowledge of the game. NHL teams are doing this already if they're smart.
