"Last weekend, IE dropped for the first time on StatCounter's charts and, according to my own personal records, is for the first time in 15 years below 30 percent market share"
Good God, how did this ever get written, and how did it pass editing? What an awkward sentence. Please, at least make an effort.
Last weekend Stat Counter showed Internet Explorer below 30% market share. According to my personal records, the last time this happened was 15+ years ago.
This took me all of 18 seconds to create. Really, just make an effort.
