I believe that the article gives a good explanation of why blogging should be an invested past time with accurate details. However I also think that though the article gives plenty of good reasons why, the cons should also be included.
Otherwise if this is the only article a person read on the matter then they would not be prepared for the worse situation. Such as, and not excluding, triggering from negative comments, obsessive compulsion to continue posting as often as possible, and slowly withdrawing from social interaction outside of the blog or internet.
Yet at the same time I really enjoyed the ideas it brought to mind. It depends on the individual.
