Hi all you ‘oh noesers’ down there.
The concept this is promoting is not new. It’s been available on SU for a long time, even before V3. What is new is this ad promoting it. It’s meant for potential advertisers to consider a new way to promote their websites. There is a button on a sponsor’s settings page that disallow the display of sponsored sites.
It’s also not only about advertising but about seeing useful things you might like since the display of which sites to show are tailored to interest. Don’t tell me none of you reads advertisements that you find interesting for one reason or another, even junk mail. You’ve probably been stumbling lots of sponsored links without even realizing it.
So don’t worry.
