Interesting discussion about this from
from the Reddit submission here. It's an interesting thread for marketers to read just to see how people think (some actual intelligent discussion surprisingly enough)...
Some interesting comments:
I think that the only real way to vote for ads is to buy something. Saying, "I like this ad" is completely meaningless to the company if you didn't end up buying whatever it is they were selling.
Au contraire, we are going to have tremendous fun when the sock puppets come out of the woodwork, up voting ridiculous adverts, and being caught, badly.
I wouldn't underestimate the reddit community. It might turn out to be extremely valuable to the advertisers to hear direct feedback from their target audience. Instead of playing the guessing game with CTRs, you can show a very simply sorted chart of liked and disliked ads.
The whole point of internet advertising is to cater to you. Let's say you are into motorcross. You like the bikes, the riders, the events. You post about this at reddit. Odds are you might be interested in ads relating to that. Maybe you want to see the new bike engines, or rims sets, or tires. But the point is that is what you like, so its marketing you can actually use.
If I can vote or comment on ads I might turn adblock off on reddit for a bit. And who knows, I might actually find an ad for something I'd like, or at least want to know more about.
