I am honored that you have asked me to elaborate on my opinion.
On the beta version I find that the type is too large, and the sans serif face, along with all the bold, really makes the screen look very crowded. True, it is sufficiently functional to see what's there, but it is confusing to the eye amd not so immediately apparent what is a post headline and what is copy -- especially with the body copy of the post in bold type. I actually find it very distracting.
I always thought (even before the Beta) that the current version was extremely elegant. There is lots of white space, and the post headlines clearly stand-out because of the serif type face in the smaller size.
Thank you, sir, for a wonderful site.
