If you start a gardening service does it make sense to hire a gardener to do your finances?
Not to be offensive, but I think a little bit of respect for other lines of work would be a good thing here.
You're comparing apples vs. oranges. I suspect a competent hacker can do a lot of things not related to coding. Per the original comment, a hacker created the most social network of the decade. I think a hacker can manage the demands of a team internally.
Because different jobs need different skill sets? Why does being a 'hacker' make you qualified or even appropriate to manage something like HR or marketing?
How many hackers are CEO's and how many of those were ever qualified for that job at the start?
The logic isn't that "any hacker is appropriate for HR work", but that a hacker who is suitible is better than a non-hacker.
Recruiting is part of HR; at fast-growing companies, it's a pretty big part. Wouldn't it make sense to hire some recruiters who are able to distinguish at least roughly between good hackers and bad ones?
