We are in the process of implementing an update that will remove the questions and forums boxes from Hubs to give them a cleaner, less cluttered interface. The Q&A and Forums sections of the site will, of course, remain unchanged.
One of the most interesting things about design is that the elements that are left out are just as important as the elements left in. A great example of this concept is demonstrated through the ma seen in traditional Japanese aesthetics- which is very present in some of the best design around- Apple products, for example.
For this reason, the HubPages team has been very careful to keep the site as streamlined as possible- removing any elements that are more distracting than functional. After analyzing some of the features that show up on the right-side of Hubs, we found that several of them were not being used by a vast majority of visitors. So we are removing the questions and forum boxes from Hubs to provide a more engaging and enjoyable experience for visitors to your Hubs. If the Hub is an Answer to a Question, then other Hubs answering the Question will still be listed.
The updated Hub layout rolls out today. We hope you like it!
