The best hubs are how-to, and share expertise. It is the most exciting if absolutely nobody on the Internet has a page about it before. That is the case for one of my hubs about playing a musical gadget called the Kaossilator. The manufacturer has a page about it, but has no practical tips. Another guy did a page, but more like a blog, so my page is quasi-unique and very organized.
The HubPage tools add elements quickly and get your page constructed fast.
