Just this week I registered a domain for myself. I've not registered any domain in several years, so it was a re-learning experience. Anyway, once I registered the domain than I had to think of where to host it. I did look at Azure, but felt that it was way too expensive for an individual. However, for a site like SQL Server Central, which must have at least hundreds of thousands, if not a million users, I think Azure makes sense. I'd say go for it.
