Responsive site: Wasted space on left side
I feel like it's a lot less wasted space than on the old site. At least for me, I'm seeing as much space as the name/bio lines take up that's completely blank on the right-hand side of the portrait image on the old site so it's like <Name/Biolines><Portrait><Blank Space> from the leftmost edge of the Name to where the post itself starts. Over on responsive, there's just <Name/Bio Lines><Portrait> and then it goes into the post itself with only a teeny bit of space after the portrait.
That said, I could get behind the idea of stacking the portraits and the Name/Bio lines, but I think it would look more aesthetically pleasing if you put the image above the name, instead of below, if done that way. Downside to that, though, would be making short posts take up even more vertical space, since even a one-line post takes up as much vertical space as necessary to display the Name/Bio lines...which, come to think of it, is probably why they're side-by-side now.
