In my opinion this type of blogging - writing about genuine personal experience, ideals, feelings - is a positive.
At the end of the day the grandfather comment is more or less correct, the internet is a cold unfeeling whatever. But the act of writing from the heart is deeply, genuinely human and in this day and age I feel that the more human things I do, the better. And perhaps by being more obviously human will inspiring others to be more obviously human, and eventually making the internet (and perhaps the world) less of a cold and unfeeling whatever.
