Ah-hem. Yes, ads now support discussions. You can comment on any running ad or read existing comments by clicking the obvious little "comment" link below it. Any time you feel inclined to, you may also peruse ad discussions on their section page.
Making an ad commentable is an option you may select when you submit your ad. I urge anyone buying an ad to take advantage of this, because it's neat. But it's up to you.
Finally, ad discussions are real stories, and will not expire when the ad stops running. They will, presumably, have scrolled off the ad section page, but any ongoing discussion will stay open and available. So it's like getting lots of free exposure.
Oh, and ad impressions and click-throughs are not counted due to discussion views. We're generous like that.
But what are ad discussions good for? Frankly, I don't know. I just think it's a cool bizarre idea, so how could we not do it?
Update [2002-3-18 21:1:43 by hurstdog]: The bug should be fixed now where ad discussions were showing up in the rdf feed from k5. Post below if you see anything else odd.

Update [2002-3-19 12:8:29 by hurstdog]: A few more bugs fixed, ads shouldn't be in digests or the story nav bar any more. Thanks for being alpha testers of my code! ;-)
