Granted, I'm a newbie to the profession, but I can't understand the snobbery towards the smaller presses.
Given that you're new to the industry, it's helpful to ask questions rather than make assumptions. There is no snobbery toward small presses. However, there are always a lot more questions regarding new small presses because they don't have a track record, so the natural questions are about their financial solvency, editing, marketing, promotion, and distribution. This is what smart authors do when looking at publishers.
The fact that this publisher uses CreateSpace means they have zero distribution - meaning their books won't be in the stores or libraries.
We don't know about their marketing and promotion, but if they're using CreateSpace for their printing services, I'd wager they don't have a lot of money to put into this end of the business. Without marketing a book, it's very hard for anyone to know a book exists.
Since they're new, we can't verify their editing talents.
In short, there are a lot of unanswered questions regarding this publisher. As such, one has to ask what makes this publisher a wise choice, considering there are many other publishers who do have a track record. It's not snobbery that makes us ask these questions, but rather, we want authors to have all the information in order to make wise decisions that will favorably impact their writing careers.
