I will if they’re interesting enough. I clicked on one in a Great Debates thread that turned out to be a recruiting ad for a Libertarian commune in New Hampshire. Not that Libertarians would ever use a dirty word like “commune,” it’s pretty much what it amounted to.
I never click on ads, whether I see them or not. If I want to buy something, I’ll go do my own search and pick from the ones that seem to be the best match. Ironically, I usually use Google for this…
I’ve cliecked on a few that were relevant, e.g. tea mail-order shops in the tea thread. A couple of them made it to my bookmark, and I’ll definitely consider them next time I’m ready to make an online purchase.
But don’t encourage everyone to do this. I believe Google will yank the ads altogether if they think that people are trying to artificially raise SD’s commision.
I have on multiple occasions clicked on ads deliberately, because of interest in the ad. In one case, it was even for a webpage I’d heard about otherwise, and had intended to check out anyway.
I have also, on multiple occasions, accidentally clicked on the ads. Whitespace is no longer safe. This is really only an issue when I already have something typed into the reply box, since clicking an ad seems to clear that when I come back to the thread.
