I like reading blogs written by one person. Maybe because that is what I do! That said, I read a combination of both. The blogs below represent the ones that I enjoy reading and the ones from which I get my best information. They are listed here in no particular order, but that may change.
Born to Run the Numbers - Great articles with even better data.
Wonkette - Just plain fun to read. I love the sarcasm and witticism.
Feministing - This blog site does a brilliant job of bringing feminist issues to the forefront. If old white men - especially OWL Guys, want to understand how feminists think, no holds barred, this needs to be a daily visit.
Twitchy - US Politics - Want to know what politicians are doing on Twitter lately? Look no further than this blog.
Hullabaloo - Captivating writing style; thoughtful arguments.
Sabato's Crystal Ball - Wow! Impressive statistics and commentary.
FiveThirtyEight - Insightful data verified commentary.
