If anything this just proves how incredibly irritating Habbo is as a company, they've managed to single handedly destroy what made fansites unique and interesting, and ultimately useful. It's hard to say what could make Habbox useful again, because it's main source of users are Habbo users, and you've got to find what they want and put it on the site, and seeing as Habbox is limited to what it can provides thanks to Habbo it does make you wonder what to do with it. It's all well and good suggesting articles, but are they (Habbo users) coming on Habbox to look at articles? They may not have a use if it's not directly linked to the place they've found Habbox from (Habbo). The only thing that does seem of use is beefing up the event/competition departments, to draw in crowds of Habbo users who, let's face it, are just looking for furniture or credits, it's what many Habbo users wanted when they joined and/or used it frequently.
The other main selling point of Habbo fansites are their unique communities which Habbo users may want to be apart of, this is probably assisted with events and competitions to draw them in and keep them interested.
After thinking about it, it does make you think that maybe Habbox is now redundant and it's no wonder the forum gets all the attention.
