N00b question but, why does my link not hyperlink :P Plz halp
For example, the idea is that most people should post the URL and then add a comment, instead of posting a personal opinion with a link at the end (like some posts in Slashdot).
But the post where the submitter is the author are sometimes an exception. I think it´s fine what you did here.
In some cases the mods press the magical button to make the link clickable. The exact conditions are not clear, it's part of the secret sauce. Perhaps it's automatic, perhaps it is manual, or perhaps it is a combination like "when the post has at least 20 upvotes but less than 3 flags, or when a mod mark it manualy".
Main reason I avoided the comments strategy was I felt it'd get lost in the sea and then people wouldn't know what the author's post is all about.
It is usually best to write a short blog post about the product and post it as a link and add a comment explaining that you are the author. It is not necessary, we would have guessed that you are probably the author, but it's a nice detail.
Reading all the thread again, for someone like me that didn't know about the "Miracle Fruit", the name of the company "Miracle Nutrition" sounds like snake oil sold by an informercial at 3am. (I think I just ignored it the first time I read the post.) If you make a web page or blog, you should explain the origin of the name and some references to the use of the fruit.
