 Let's mark any Q/As with `WIP` when the answer is long, complex, and likely to evolve over time. It is very important to signal when we think something is roughly "a final answer", versus "a place to jot down notes and point others for quick disambiguation". Many answers, like comparisons to other systems, will be WIPs for a while.
 
+#### Closing issues
+
+We try not to close issues that have been answered adequately; leaving them open makes them more easy to search and find, and improves visibility. Instead, mark the question as 'answered'. Issues should be closed, however, if they are duplicates, irrelevant, or poor quality. Sometimes we will maintain, curate or edit an issue to ensure higher quality, too; we'll post in the issue when we do that.

 #### Rendering to a page
 
 All these questions and answers will be compiled into a webpage rendered at http://ipfs.io/docs/install (still TODO)
