welcome to the forum antonyz..wow a poll on your first post eh?
you may wish to read the stickies and become further edified on where to post what topic
for example - this topic would be better in the nutrition section, not in the supplement section
to answer your question in a quick nutshell however, yes stevia is becoming more and more common around the world, has actually been around a very long time....is popular due to the fact it has up to 300 times the sweetness of sugar, has negligible effect on blood glucose and therefore is becoming a very popular option for lower carbohydrate-controlled diets
a quick search of wiki will give you very nice synopsis of this one
take care
