Ollock's
Jed Blog. It's the blog of a human, Vinceon, who's been Marysued into Ollock's (very interesting!) conworld. It feels so good to read about a sci-fi world that's had this much detail and work put into it. Well, there's really no story -- it's all about the world(s), and that's what makes it so cool. Plus, y'know, the good writing and all that.
SurgeonsBlog. This guy, too, can write (and how). Introspection, extrospection, enough gory details to get the point across but not enough to put tons of people off. Reality.
