This is how I think about it:

* There are 3 sets of issues: [1] sponsoring, [2] kickstarting and [3] feedback.
* An issue belongs to [1] if it has an offer (regardless of its state being REVOKED or EXPIRED)
* Thus, sets [1] and [3] might intersect (when someone sponsors a feedback issue)

Home page must display [1] and [2]
