Is it just me or the author of this blog post has a very annoying way of writing? He keeps explaining things and then a couple of lines below he writes something like "remember the discussion above?" or "if you remember correctly ...". Hell, sure I remember, because I just read about this 10 seconds ago. Do people really have such a short attention span and can't remember what was in a previous paragraph? Repeating stuff over and over seems almost like content farming to me.
