Like you, I don’t want to divert Kari’s post. However, I think the discovery methodology is quite suspect.
Give people 50 pieces of candy and many will save them like precious stones - not me mind you but many. If you said, “I’ll give you 50 more when you eat all 50…” then you would have a better view of which ideas are really important. Spreading 50 votes over 2000+ ideas cannot ever possibly measure true demand. Why 50? Why not 25? 10?
Ideation is different than backlog. Separate the two if you really want input from the users. There should be no limit to ideation. There can and should be limits to the backlog however.
One of the oldest ideas which has been in the top five for years has a status of “Gauging Interest”. If that’s the case, voting seems pointless. 
Maybe we should enter ideas on the portal but not vote for anything. That would certainly stop the complaining on this topic!
