As a follow up to this etymology question, does "so far, so good" carry a negative connotation?

For example, after having her sonogram, my wife asked the technician if everything was okay.  The technician replied, "so far, so good."  My wife later remarked that she didn't like that the technician used the phrase because it sounded like things will be going wrong later.

I always thought this phrase was positive and that it was a replacement for the word "good."


Question: Is there a difference between "brainstorming" and "mindstorming"?
Answer: "Brainstorming" is a commonly used and commonly accepted word. "Mindstorming" is not. As far as I can tell it means the same as "brainstorming", and thus it is difficult to see why we need a new word to express an idea that we already have a word for. (IMHO it's just an effort by some people to sound like they're introducing a new idea when they're just recycling the same old ideas, but that may be getting off topic.)
