Previusly (and please you can add suggestions at any time in the future - I get e-mail notifications so I will get the message):
Eschaton? While most of Atrios' posts are just links, it is one of the major liberals blogs.
Eschaton is listed, of course. You must have missed it.
Egg - like a bird's egg is the new blog by Chris Leonard, formerly of Elsevier and now with BioMed Central / PhysMath Central.
Sorry Coturnix, for some reason I looked under 'Ec' not 'Es'
