How do I suggest a new Badge?
Here, on Meta, by asking a question that describes the proposed name of your new badge, what criteria we would use for awarding it, and what purpose it would serve.
On stackoverflow I did not see a badge for effective posting
I don't know what you mean by "effective posting". We have lots of badges for useful posts; that's what practically half or more of the badges are about. We're all about content and the system is set up to reward those who post valuable content.
which may apply to your other site that do Q & A.
I'm not entirely sure what you mean by this either, so I'll throw a couple of different explanations at the wall and hope that one of them will stick:
- Badges are the same across all Q&A sites in the Stack Exchange network, because all sites have the same fundamental goals and purpose.
- Badges are not awarded on one site for participation on another site; each of the sites function basically independently. If that's what you're proposing, it has been proposed before, on several different occasions.
I think there should be a 'Badge' for n number of times a user references a link to a stackoverflow post that either answers the current question or provides good follow-up information relevant to the answer or implementation.
We already have a series of badges that serve essentially the same purpose:
is a bronze badge for users who shared a link to a question that was visited by 25 unique IP addresses
is a silver badge for users who shared a link to a question that was visited by 300 unique IP addresses
is a gold badge for users who shared a link to a question that was visited by 1000 unique IP addresses
You can see a list of all the available badges on the Badges page in the Help Center. (This works for any site, not just Stack Overflow, but like I mentioned above, the list will be the same for all sites.)
This would save some space and decrease the number or similar Answers and Answers would be improved via editing.
Duplicate answers should not be posted at all. If a question is a duplicate of another question, it should be flagged and closed as such.
Otherwise, there's nothing wrong with similar questions and answers. We're not worried about the space, as long as it's used in the service of useful content.
