I've been running a publicist badge experiment lately.
I think it is safe to say that there is a strong benefit to sharing most of the questions.
However, is it worthwhile to reward users for sharing gimmicky closed questions like "What's your favorite programmer cartoon?"
Is there a net benefit to the site, or does it bring people to the site in the wrong way?
I think the answer is: probably not worth it. They probably shouldn't count towards sharing badges. As it stands, there is an incentive to share such questions because they are indeed very interesting to many.
- There may be another category of questions that shouldn't apply, such as some locked questions. What is your best programmer joke?
- This experiment involved rapidly sharing questions on relevant subreddits and hacker news. This lasted about 9 days and was enough to generate some backlash from reddit. I do not recommend sharing questions in this matter, especially over a prolonged period, as it can impact other communities' views of SO in a negative way.
