Let me explain my preferences with an analogy.
I used to work in a bookstore where they sold Bibles. Some of them were some of Cambridge's most luxurious calfskin editions, which came in special boxes for more than $ 100 each. Some of these were mass-market brochures for $ 1.99 each. In cheap ones, gross grammar and spelling mistakes were often found. I do not think this is a coincidence.
No matter where my software will be used or what it is intended for, I try to do my best to make sure that it gets (metaphorically) to a high-quality, expensive rack. Everytime. Even with the risk of sounding "too formal."
