-<p>We have had a quick glimpse at using gatherers with Groovy.
-We are still in the early days of gatherers being available,
+<p>It is great that Groovy has a rich set of methods that
+work with collections. Some of these methods have stream
+equivalents, and now we see that using gatherers with Groovy,
+we can emulate more of the methods.
+Not all algorithms need or benefit from using streams,
+but it’s great to know that with gatherers, we can
+likely pick whichever style makes sense.</p>

+<div class="paragraph">
+<p>We are still in the early days of gatherers being available,
so expect much more to emerge as this feature becomes more mainstream.
We look forward to it advancing past preview status.</p>
