As a proud Apple fan, I would like to use Apple product even on the server side. I was asking a question about clustering Apple Mac Mini servers, and one user asked: "Why do you want to use Apple Mini Server?". Just as a rule of thumb for my future questions, do I need to explain myself on why I would like to use Apple-based products?
Comments are (among other things) intended for asking follow-up and clarification questions to a post, in your case the question you've asked. I understand the comment primarily as an inquiry about any functional needs to run OS X on your server (e.g. you are developing a server component with Objective C or are you planning to deploy this into an all-Apple environment). Clarifactions like this can help to improve the question and its constraints, which usually results in better answers.
