Doing personal web sites is a never ending task as each little nugget of information that is learned must be applied somewhere; every change in fashion assimilated; every cool hack found a use for. Not all are for the better, but with each one a little more is learned through application, and that is the point.
Academic learning is one thing, application is another.
