Gaining financial value on the work done by someone else is a very dubious thing. Also the legal implications also scare me. You could perhaps argue the value was in the work that was taken to find and share but the person on the other side (the one who created the thing you shared) may not feel the same and who knows... could they say it with a lawsuit? Also do we really want to bring in something that we're always fighting about and our answer is to just bring in more downvoting... that hasn't ended well so far.
Communities really do need the ability to share outside content because no community system that is successful right now is successful without it. However we have to be careful because of the unique reward pool aspect of hive. Then again if you create a good community you will have people motivated by much more then a few cents of limited reward pool inflation.
