9. Paul Thurrott (http://www.winsupersite.com/)
Want to know what the 2874th line of your Windows Registry really means? Paul Thurrott will tell you. In a seven-part, 5000-word blog post (bonus: with screenshots!). But Thurrott is perhaps most notable for his tendency to compose angry-sounding blog entries aimed at anyone who dares criticize Windows, as demonstrated in this hilarious blog by one of Thurrott's targets, ZDNet's Ed Bott.
10. David Coursey (http://www.pcworld.com/businesscenter/blogs/tech_inciter.html)
Holier than thou and--more important--smarter than thou, Coursey (the "Tech Inciter") pushes the hot-topic buttons of the day while expounding on his superior knowledge of everything from iPhone architecture to how the First Amendment should be interpreted.
Of course he does all this for PC World, so we forgive him: He may be an opinionated loudmouth, but he's our opinionated loudmouth.
