Actually it occurs to me (and perhaps to others too, haven't scanned this whole thread) that a point reward for bands making it from the wish list to the official DLC is a bad idea.
It would encourage people to vote on most likely candidates (bands at the top of the stack that aren't Led Zepelin and Pink Floyd et al) and stilt the whole process because people will be backing the likeliest horse to win the race and not bands they truly wish to see make it into DLC.
Again, it seems pretty much a no brainer so if it's been mentioned in this thread already then let's just say I agree.
All the points/days are flexible. I just wanted to put the framework in the post.
The problem with giving people points when an artist on their list gets a release is that it skews the results... Anyone who has taken a high school stats course could tell you that. The list loses its authenticity as a truly global list because some people have more of a voice than others. That'd be like taking a survey and counting someone's response twice in your data.
I think the fairest thing to do is not give out any points at all... If you give out points on a regular basis, then that also introduces a skewing in your data, at least for the all time list. What's to say that everyone who uses the app will use their additional points? Slim to none.
I suggest that you keep the all time list and not give out additional points.. People can change their list based on what DLC has been released. That is the fairest and most statistically accurate way to do it.
But you need a reason to get people to use it regularly. Not giving any points will cause most people to set it and forget it. If you give out points for regular use you are encouraging people to be active and allowing everyone an equal opportunity to get more points.
And to keep it somewhat in check you limit to point cap and implement point drain for people who become inactive.
Finally got a band on my list!
Time to pick a new band.
Does that mean you got more points?
