Slashdot? I read HN.
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.
It is likely Slashdot will still be here when HN is gone.
There's a lesson in that.
They're sinking in the last year or so while HN is rising somewhat.
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.
For me, Slashdot lacks the buzz it used to have.
