-Inter-diffing -- what changed *between* two rounds -- is planned!

+Rounds are a far superior to standard branch-based
+approaches:
+
+- Submissions are immutable: how many times have your
+  reviews gone out-of-date because the author pushed commits
+  _during_ your review?
+- Reviews are attached to submissions: at a glance, it is
+  easy to tell which comment applies to which "version" of the
+  pull-request
+- The author can choose when to resubmit! They can commit as
+  much as they want, but a new round begins when they choose
+  to hit "resubmit"
+- It is possible to "interdiff" and observe changes made
+  across submissions (this is coming very soon to Tangled!)
+
+This [post](https://mitchellh.com/writing/github-changesets)
+by Mitchell Hashimoto goes into further detail on what can
+be achieved with round-based-review.
 
 ## fine, we'll make a patch ourselves
