The Q&A section could be improved in several ways, I am listing some ideas here.
* When clicking on an answer in the "community content" tab on the frontpage one is sent to a page displaying the answer only, with no possibility to read the question or other answers. I think the link should lead to the relevant question/answer thread and highlight/indicate which the new answer is.
* answering and commenting are closely related, and it is not always clear if one should use one or the other. should we merge the two?
* comments should be listed next to the question/answer they are referring to and not at the bottom of the page.
* Similar to the forums, we should probably have sections and subsections sorted by topics. What do you think?
