It occurred to me that incoming links to posts may be a solid quality and/or relevance criterion. Hence, I propose a (set of) badge(s) should be added to highlight posts that are linked to more often than usual.
Similar to other badges, there can be three levels with progressively larger numbers, creating sets of bronze, silver and gold.
There are different types of links to consider:
- Linked from a duplicate (applies only to questions).
- Linked from a post on the same SE site.
- Linked from a comment on the same SE site.
- Linked from a post on any SE site.
- Linked from a comment on any SE site.
- Linked anywhere on the internet.
The the last is easy to game and already represented by the Announcer/Booster/Publicist trio, I think we can savely disregard it.
As for the others, I think one can reasonably draw the line at any point, or even create different badges. A question with many duplicates may have very different qualities from one that is mentioned in many different contexts.
Even though I'm more interested in the principle, here are some concrete proposals (don't give me crap for the names, and the numbers certainly require tuning):
- Foresight/Prescience/Oracle: question has 5/50/200 duplicates
- Handout/Article/Textbook: post linked from 20/100/500 posts on the same site
- Connective/Interdisciplinary/Fundamental: post linked from 2/5/10 different SE sites
Possible reason against: There are already badges for "good" posts. -- Why, yes, several in fact: there are badges for views, votes, and favorites. None of these capture how relevant a post is to other posts, and can one more hurt?
