There will always be some problems, like in many things that involve people with their liberty of doing something; so locking nodes doesn't seem a solution to me.

May be it would be helpful to know the reason of a vote, just to be informed and LEARN from my errors. I really appreciated people who told me why they wanted to downvote what I wrote.

Finally, I understand XP listed in our homenodes, but what is the meaning of Reputation, if you can't see reputation of nodes that you didn't vote on?
