Another blog to share - Future Perfect - although it seems more of a story than a blog. When it was last updated - December 2008, One hour ago, December 2015 - I don't know. All I do know is that I'd give my left leg to be able to write at the quality of its writer, Ariadne. It's a class act, made all the classier by black-and-white boobs.
The science fiction world building in particular is extremely commendable.
