Usually I'd laugh at the silly comments in this HN thread:http://news.ycombinator.com/item?id=5201981
1) I've just woke up with a bad headache and I'm cranky
2) It feels like this kind of thing is happening a lot recently
I'm not going to set out why SEO is valuable, anyone that follows me probably gets it. If you do not, please tell me and I'll explain when I'm less cranky.
I am getting tired of this now though, there are reasons why our industry is under this kind of attack (part of it is our own fault) but that's a post for another day.
