A real developer who loves his project would never outsource major aspects of the project. One might outsource the design, only because its incredibly difficult to create a great UI and have the know-how to code it as well.
One might outsource the slicing of a layout to CSS/HTML or something simple like that while dealing with IMPORTANT issues such as database architecture, setting up the server, etc.
To suggest that you want to concentrate on the "business aspect" simply means that you don't want to do the hard part. By outsourcing, the article states: "I have more time and I can spend this time for marketing and blogging". ... Right. Because blogging and marketing is so very tough?
The truth is that you USED to be a developer. It sounds like you've realized this and outsourced the project to an actual developer. If that's the case then you've made a wise choice.
In any case, best of luck to you.
Edit: It sounds as though I am belittling other people's jobs on a project. Sorry, I guess to some degree I am? I agree that I am a bit foolish to say that. I don't mean to create any type of hostility in this thread. (Regardless I will keep my full comment here so this thread makes sense.)
My main point is that the author refers to himself as a DEVELOPER. Therefore it does not make sense to me to outsource his own specialty.
