They still do.
I'm the kind of guy they want. I post AC and don't have a profile, but I do click on ads. I have bought stuff through those click throughs. I support Slashdot by supporting their advertisers because I value the resource Slashdot provides me. Frankly I'm not a fan of the beta, but I think Slashdot's look is dated and clunky, so something new is at least welcome.
If you're the kind of guy they want, that's a shame, because I've been on this site for over half of my life (this is my second username), and I have a fucking STAR beside my name that means that I give MONEY to this site. And I am ready to move on to backslash or whatever the new site ends up being called if Dice Beta becomes the standard layout.
