I don't know yet, at the moment I plan to open a public community section (forum) first. I'm still thinking whether to open it separately under namecoin.pro or as a subsection of another community portal. Creating pages/blogs will of course be possible. But at the moment I don't plan to offer full hosting services for .bit websites. But a .bit mail system is on my to-do list.
A forum about all decentralized dns projects, including namecoin, would be good, and could hit it big if there is ever some surprize news regarding centralized dns. It would probably never happen, but having a site set up awaiting such an unlikely even would be like holding a smart lottery ticket.
Still, it seems the big roadblock is that the cost is denominated in nmc, and the second roadblock is simplicity since the process has to be very simple to ever catch on, and a third roadblock is that social things like web networks need to reach a critical mass of genuine users before most people have any interest.
The third issue is always solved in the crypto community by building fake user bases and incentivizing them with cash. That works well with shitcoins that are designed to disappear once the dev can cash out, but most people spot that kind of fraud.
