Basically, add a new question view: Common. This would contain questions that have had both 10 or more upvotes and have 1 or more other questions closed as duplicates.
- which way is better “null != object” or “ object != null”?
- Can you build an iphone app on windows?
- Does a Tool exist to parse SQL to Linq queries?
- How do you specify empty strings?
I suspect some at least can be avoided by adding the "Common" view for questions and a note in the FAQ to direct users to it.
