Anyone know what's up with "Slabo 27px"? Looks like its recent usage is much lower than other fonts with similar totals (it's at 800m views in the last 7 days while the fonts above and below it are all ~4b). Also the only font I haven't heard of in the top 20, though maybe I just happened to miss it every time.
