I'm lucky in that I have a somewhat more open relationship with HN; HN allows me to view other sites, and in return I let HN have more users than just me
I scan the RSS feed, ignore the dupes from HN, reject the political stuff, and glance over the remaining tech headlines.
Of the three that might appeal to me, I read the abstracts, and occasionally follow the links to the original articles. I ignore the comments because I never log in anymore. The only ad I might see is in the upper right.
The new design seems to confirm that I'm not alone.

My gut feeling says no. I used to read Slashdot as much as I now read HN or Reddit. I hardly ever go there any more, and when I do it just doesn't seem interesting.
