G+ Web Update Sept 9
We're rolling out two new features on the Google+ Web app today. First, when joining a Community on the recommended communities page, we'll reveal a number of related additional suggestions.
Second, search autocomplete suggestions are now significantly faster and include personalized recommendations like collections you own, communities you've joined, and more relevant results specifically for you. Of course, you can still access full search results in addition to these autocomplete shortcuts which are intended to get you to what you're looking for faster.
As always, please keep sending us your ideas/issues using the Send Feedback menu item.
