Well said. It won't be just right for every purpose. Finding a host that caters to every want and need is hard work but the unique advantages may be just right where privacy and control of ones own data is a high priority.
As free hosting, it is an option that does not have the disadvantages that come with other free hosing because the motives of the developer are not the same as a corporate host provider. Depending on background, it might not be so easy since it does not appear to have all of the extras that attract inexperienced site builders but if learning to build from scratch, this could be great.
