I say it because many people are unaware of it. It has helped me many times when I needed a simple answer and didn't take up the time of someone who could be helping someone else with a difficult question. You are correct, the forum does create discussion. I'm very thankful to have the experts helping me when I need it. I'm pretty certain nobody knows whether you are sitting at a pc or walking into a store when you post, and rarely have I seen where more than a few minutes are needed to browse the search query to find the answer I am looking for. My time is valuable to me also.
Personally I wouldn't use stevia, I'd let the juice sit in steep for the four days it takes to get proper product ordered and delivered to my door.
