That list reads more like a "21 books that I've read--with a few girl authors I heard were good or famous or black thrown in".
Brent Weeks is not a great author, and while Jim Butcher is consistent in his output (barring the few years where his RL went to shit on him) his Craft suffers in his non-urban fantasy series. (He coasts a LOT on Harry Dresden's voice and charm and culture references, and doesn't get that crutch in his other series and it shows.) I LIKE Jim Butcher, but there's tons of authors that can write circles around him. His career is based on completing books and getting them out the door, not creating masterworks.
Where's Robin McKinley? Robin Hobb? Kate Elliott, who was writing and COMPLETING her Crown of Stars epic fantasy series at the same time Martin and Jorden were writing (and never completed their series)? Lois McMaster Bujold, whose Challion series is just as good as her Vorkosigan series? Jacqueline Carey? And if we're including YA, which the Hunger Games suggests (although as one person pointed out, those are sci-fi), where's Tamora Pierce? Patricia C. Wrede?
The person who wrote that list reads a very specific part of the genre and leaves a LOT of the greats out.
