Votes in the forum would be easy to open up because you're correct, when I originally coded it up it was going to allow for a "floating box" on the thumb to list the users - but there was an immediate buzz-saw I ran into when that functionality first went live (even having people named in the notifications caused pushback!), so I was forced to go the other direction (just show counts and also allow users to not be named in notifications). The data is still there and it would probably only take a couple of hours to turn it around, but I still sense a great deal of friction towards doing it and so it's not a can of worms I think I want to open.
Articles would probably take a bit more effort, but for the same reasons surrounding the negativity with forum votes - I'm not sure it's a good idea. Again, I do agree with wrapping some limitations around the up/down voting for Supporters so that they don't have unlimited power - it would likely force them to put more consideration into the posts they "super" up or down vote. Unfortunately, it's just not something that could be coded up in a few minutes...
100% i think this would be the best way forward for now to see how it goes. Id imagine it would fix one of the biggest problems with the voting system atm as then supporters would only use them votes for something they really believe in other than trowing them around like the is no tomorrow.
I also think the limit should include both up votes and down votes and not give a separate number to them, so for instance lets say a user has 10 extra votes (Not a hard number just an example you guys can come up with what would be the best total) a month that would include both up and down votes in that number.
