Anyone know why CMH seems to use the north runway almost exclusively?

Every time I look at flightradar24, I only see arrivals and departures on the north runway 10L/28R, not the longer south runway 10R/28L. I've even seen arrivals going out of their way to get in line behind 2 or 3 other flights on final to 10L, while 10R goes completely unused. What's the deal?
