I'm an Ottawa-based casual contributor to Wikipedia primarily in the areas of sports -- I update a lot of tennis rankings in each player's infoboxes -- and pages of local interest. My pet-peeves are pages with excessive unimportant details, irrelevant information and pages on which every sentence begins with "On such-and-such a date, xxx happened."
I also seem to find myself updating verb tenses frequently.
Unfortunately, due to a career shift (as of January 2015), I no longer have much time to dedicate to Wikipedia. I will continue to dabble here from time to time.
