Well, could not help posting this one. Google Pages disappointed me. It is plain old website hosting with an “easy HTML editor”. I would have expected Google to add more value by having something akin to a simple content management system, where I could choose a template, so that navigation links and consistency of look and feel in my website would not be my headache. And yes, ensure that you do not make an website with your primary GMail account. Its a source of spam because the URL has your login name in it.
One positive is that since it is Google, I do not expect it to disappear over night, as some of the other “free and ad-free” hosts have done in past.
