This is an interesting idea. However, it may be too big for any real income potential. This would be better suited to a private group of no more than 500 people with a max post count per person per day. I have posted 3 articles with Vincentb and have earned less than .05 cents per post. I am spending hours upvoting others and it appears they are experiencing the same approximate gains. I will keep an eye on this idea for awhile though. Some people may get tired and thus will decrease the use of the tag and increase the profits per tagged post.
