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?
