I had tweeted Ryan the suggestion of writing this post yesterday and am delighted that he's published it already. I was considering hiring employee #1 for WP App Store and this post has given me some extra confidence that the time is right. Thanks again Ryan. I'd love to hear experience and advice from HN'ers on this topic as well. Fred Wilson, perhaps a post of your own?
I haven't drafted the job posting yet, but if you're interested, sign up to the email newsletter at http://wpappstore.com and I'll send out an email in the next couple of days.
