Hi, author here. Indeed I try really hard to see it from the recruiter's point of view, which is what the article is about. And I don't think other devs have any problems to see it from the recruiter's point of view either.
Of course it's a sales job. Of course it involves calling/mailing a lot of people and getting a lot of "no"s. Of course the developers are not the customers in this relationship.
What does that have to do with the IT competency of the recruiter though?
I don't buy the "it's a sales job so it's ok if they do it quick and dirty and don't take the time to educate themselves". In my opinion, the opposite is true - recruiters would be much better salespeople with a higher success rate if they showed more competency in the field they work in, both to their customers/clients and to the candidates.
